Quick reference

Criminal Law

  • Actus reus plus mens rea: a voluntary act (or a breach of a legal duty) combined with the mental state the statute requires; a status or an involuntary act cannot be punished.

  • Larceny = trespassory taking and carrying away of another's personal property with intent to permanently deprive the owner.

  • Robbery = larceny taken from the person or presence of another by force or fear; armed robbery adds a dangerous weapon or an article the victim reasonably believes is dangerous.

  • Burglary requires a breaking and entering of a building with intent to commit a felony or larceny inside; entry into a dwelling carries the highest penalty.

  • Assault is either an attempt to commit a battery or placing another in reasonable apprehension of an immediate battery; battery requires unlawful, non-consensual physical contact.

  • First-degree premeditated murder requires premeditation and deliberation; felony murder requires a death caused during the perpetration of an enumerated felony.

  • Michigan self-defense (MCL 780.972): deadly force is justified by a reasonable belief of imminent death or great bodily harm; a person lawfully present and not engaged in crime has no duty to retreat.

  • Felony versus misdemeanor is fixed by the statutory maximum: a misdemeanor is punishable by not more than one year in jail, a felony by more than one year.

Criminal Procedure and Constitutional Law

  • Fourth Amendment: searches and seizures must be reasonable; a warrant requires probable cause supported by oath or affirmation and must particularly describe the place and the things to be seized.

  • Terry stop: reasonable suspicion of criminal activity based on specific, articulable facts; a frisk additionally requires reasonable suspicion that the person is armed and dangerous.

  • Search incident to arrest: the arrestee's person and the area within immediate control (Chimel); a vehicle passenger compartment only if the arrestee is unsecured and within reach or evidence of the offense of arrest is likely inside (Gant).

  • Automobile exception: probable cause to believe contraband or evidence is in a vehicle permits a warrantless search of the vehicle and of containers that may hold it.

  • Miranda applies to custody plus interrogation; the waiver must be knowing, intelligent, and voluntary, and an unambiguous request for counsel ends questioning until counsel is present or the suspect reinitiates.

  • Exclusionary rule exceptions: good-faith reliance on a warrant, inevitable discovery, independent source, and attenuation.

  • Sixth Amendment counsel attaches at the initiation of adversarial judicial proceedings (formal charge, preliminary hearing, indictment, information, or arraignment), not at the moment of arrest.

  • Michigan warrantless arrest: an officer may arrest for a felony on reasonable cause; misdemeanor arrests generally require the offense to occur in the officer's presence, except domestic violence (MCL 764.15a), which mandates arrest on probable cause.

  • Arraignment must occur without unnecessary delay; Michigan court rules set the preliminary examination at 14 days after arraignment in custody and 21 days when not in custody, absent waiver.

Patrol Procedures and Officer Safety

  • Reaction gap: an officer's decision-and-trigger time exceeds a suspect's reaction time, so distance, cover, and readiness determine survival.

  • Traffic stop positioning: offset to the left and slightly behind the violator's vehicle, angle the patrol car, and use the passenger-side approach when circumstances favor it.

  • Cover stops projectiles; concealment only blocks observation; officers should move to cover before issuing commands.

  • High-risk stop sequence: broadcast location and plate, wait for backup, use the PA, order occupants out one at a time, and have each walk backward to a designated location.

  • Handcuffing: search before and after cuffing, apply cuffs double-locked and checked for tightness, and never leave a prisoner unattended.

  • Use of force is measured by Graham v. Connor objective reasonableness: severity of the crime, immediate threat to officers or others, and active resistance or flight.

  • Tunnel vision and auditory exclusion are normal stress responses; officers must consciously scan, breathe, and reassess the scene.

  • Domestic violence calls: separate the parties, interview separately, photograph injuries and scene, and in Michigan arrest is mandatory when probable cause of domestic assault exists (MCL 764.15a).

  • Pursuit: weigh the need to apprehend against danger to the public; policy-compliant pursuits require continuous radio updates and termination when risk becomes disproportionate.

Investigations and Evidence

  • Corpus delicti: independent evidence must show that the charged crime actually occurred; a confession alone cannot support a conviction.

  • Chain of custody records every transfer of evidence from seizure through trial; a break generally affects the weight of the evidence, not its automatic admissibility.

  • Best evidence rule: the original writing, recording, or photograph is required to prove its contents unless an exception applies.

  • Common hearsay exceptions: excited utterance, present sense impression, dying declaration, statements against interest, business records, and public records.

  • Photo lineups should be double-blind where feasible, use fillers matching the witness's description, and include no comment or cue indicating which photo is the suspect.

  • Crime scene sequence: secure and protect, photograph and document before moving anything, then collect and package with proper seals, labels, and initials.

  • Entrapment requires government inducement plus a defendant not predisposed to commit the crime; furnishing an opportunity alone is not entrapment.

  • A K-9 sniff of a vehicle's exterior is not a search (Illinois v. Caballes), but prolonging a stop beyond its original purpose to await the dog violates Rodriguez v. United States.

Quick reference

Traffic Law and Enforcement

  • Michigan OWI: operating with a bodily alcohol content of 0.08 or more; 0.17 or more is high BAC with enhanced penalties.

  • Under-21 zero tolerance: 0.02 or more bodily alcohol content is prohibited; commercial vehicle drivers are held to 0.04.

  • Implied consent: a lawfully arrested driver must submit to a chemical test; refusal triggers a license suspension and the refusal may be used at trial.

  • Michigan requires a written crash report when a crash involves injury, death, or property damage of $1,000 or more.

  • Pennsylvania v. Mimms permits ordering the driver out of a lawfully stopped vehicle; Maryland v. Wilson extends that authority to passengers.

  • Basic speed law: speed must be reasonable and prudent for existing conditions regardless of the posted limit.

  • Michigan move-over law: move at least one lane away from a stationary emergency vehicle displaying flashing lights, or slow to a safe speed when a lane change is unsafe.

  • Seat belt enforcement in Michigan is primary for front-seat occupants; an officer may stop a vehicle solely because an occupant is unbelted.

  • Speed enforcement requires articulable observations (pacing, radar or lidar with calibration and operator certification) plus documented road and weather conditions.

Juvenile Justice

  • Michigan juvenile court jurisdiction generally covers persons under 18 at the time of the offense (raise the age); specified serious offenses may be waived or designated to adult court.

  • Status offenses (truancy, running away, curfew violation, incorrigibility) are not delinquent acts and are handled through the court's status jurisdiction.

  • A juvenile taken into custody: notify the parent or guardian promptly and bring the juvenile before the court without unnecessary delay; Michigan requires a detention hearing within 24 hours.

  • Juvenile Miranda waiver is judged on the totality of the circumstances: age, education, intelligence, prior contacts with police, length of questioning, and presence of a parent or interested adult.

  • School searches require reasonable suspicion rather than probable cause (New Jersey v. T.L.O.); more intrusive searches require a correspondingly higher justification.

  • Juvenile records are generally confidential, and fingerprinting and photographing are limited to circumstances specified by statute.

  • Juveniles have a right to counsel in delinquency proceedings; a waiver of counsel must be knowing, intelligent, and voluntary and placed on the record.

  • Designation and waiver: Michigan permits adult prosecution of juveniles for enumerated offenses at specified ages, and designated proceedings allow an adult sentence while juvenile jurisdiction is retained.

Civil Rights

  • 42 U.S.C. § 1983 requires conduct under color of law plus deprivation of a right secured by the Constitution or federal law.

  • Qualified immunity shields officers unless the violated right was clearly established at the time of the conduct.

  • Excessive force is judged by objective reasonableness under Graham; deadly force requires probable cause of a significant threat of death or serious physical injury (Garner).

  • Equal protection prohibits selective enforcement based on race, ethnicity, religion, national origin, gender, or other protected class status.

  • The First Amendment protects speech and assembly; officers may not retaliate against a person for protected activity such as recording police in public or filing a complaint.

  • Ethnic intimidation (MCL 750.147b) makes malicious intimidation or harassment based on race, color, religion, gender, or national origin a felony.

  • Duty to intervene: an officer must stop excessive force by another officer when in a position to do so and must report the conduct.

  • Bias-free policing: stops must be justified by observed behavior or specific information, not by a person's appearance, group membership, or presence in an area.

Quick reference

Professional Conduct

  • Truthfulness in reports, affidavits, and testimony is absolute; knowingly false statements can result in criminal charges and loss of licensure.

  • Brady: exculpatory and impeaching information must be documented and disclosed; an officer who suppresses it jeopardizes the prosecution and the case.

  • Garrity: statements compelled from an officer under threat of discipline are inadmissible in a criminal prosecution of that officer but may be used for administrative discipline.

  • Use of force reports must state the specific facts that made force objectively reasonable, the force used, injuries observed, medical aid rendered, and witnesses.

  • MCOLES licensure requires compliance with commission standards and training rules; a felony conviction or specified misdemeanor disqualifies a person from licensure.

  • Secondary employment, gratuities, and gifts create conflicts of interest and are regulated by agency policy and Michigan law.

  • Confidential informants: corroborate information, document payments and contacts, and protect identity consistent with agency policy and court orders.

  • Sexual harassment and inappropriate relationships with victims, witnesses, or complainants violate policy and may constitute criminal sexual conduct.
