PA Private Investigator common mistakes
PA Private Investigator · Understand the traps and how to avoid them.
Treating the Pennsylvania Private Detective Act of 1953 as a general licensing statute and answering questions about conduct, employment, and registration without citing the specific section that governs each, instead giving a blended 'the Act requires it' answer.
Candidates study the Act as a single narrative and never build a section-by-section map, so under exam pressure they default to vague references rather than the operative provision, and they miss questions that turn on which section actually controls (licensure versus registration versus conduct).
What to do instead
Build a one-page section map of the Act organized by function: who must be licensed, who must be registered as an employee, what conduct is prohibited, what records must be kept, and what the licensing authority may do. For each section write one sentence stating its operative rule and one distinguishing fact pattern. Drill by reading a fact pattern and naming the controlling section before reading the answer choices.
Assuming that because a person holds a private detective license they may perform any investigative service, including acting as a guard, running a protective detail, or conducting employment background checks, without checking whether the license class or a separate registration covers that activity.
The word 'license' suggests a general permission, and candidates transfer assumptions from other states or from other Pennsylvania licensing schemes. They also overlook that the Act distinguishes the business licensee from individual employees who must be separately registered.
What to do instead
Memorize the distinction between the business entity holding the license and the individuals who must be registered to act under it, plus which activities fall inside versus outside the licensed function. Practice with short scenarios asking 'who must hold what, and what must be filed before this activity begins,' and answer in that two-part form.
Answering that a licensee may use any technique a police officer could use, or conversely that a licensee has no more authority than any private citizen, without distinguishing the source of authority in the specific scenario.
Candidates collapse two different questions: what a private investigator may lawfully do, and what a police officer may do. They also forget that a private investigator's authority generally derives from the client's consent and property rights plus citizen authority, not from state police power.
What to do instead
For every powers question, ask three things in order: whose property or consent is involved, is a citizen's arrest or detention privilege actually triggered, and does any statute specifically authorize or forbid the act. Write out the citizen's-arrest and detention limits and the trespass and consent boundaries as separate flashcards rather than one 'police powers' card.
Applying search-and-seizure rules to a private investigator's evidence gathering as if the Fourth Amendment and the exclusionary rule governed the conduct directly, and concluding that improperly obtained evidence is automatically inadmissible.
Candidates overlearn criminal procedure from police-focused study and do not internalize that constitutional search limits generally constrain government action, while private conduct is governed by trespass, privacy torts, wiretap statutes, and agency or licensing rules. The state-action question is the usual trap.
What to do instead
Study the state-action doctrine explicitly and build a decision tree: is the actor a government agent or acting at government direction, if not then which statute or tort governs, and only then ask about suppression. Practice fact patterns where a private investigator later hands evidence to police, and identify at what point state action could attach.
Describing chain of custody as 'documenting who handled the evidence' without specifying the elements a court actually tests: each transfer with date, time, and purpose, tamper-resistant packaging, storage conditions, and the ability to account for every gap.
Candidates memorize the phrase rather than the mechanics, so their answers sound correct but omit the elements graders look for, especially the unbroken-gap requirement and the distinction between chain-of-custody documentation and the separate question of whether the item is what it purports to be.
What to do instead
Write a model chain-of-custody entry from scratch, including item description, unique identifier, collector, date and time, location, packaging and seal number, and every subsequent transfer. Then practice explaining in one paragraph how you would respond to a challenge alleging a two-day gap, focusing on what records close the gap.
Answering surveillance questions by describing what to observe and how to record it, while omitting the pre-surveillance legal and operational planning steps such as confirming the lawful basis for the location, establishing the objective, and planning for detection and disengagement.
Surveillance is the most intuitive domain, so candidates answer from general instinct and skip the planning layer that exam questions reward. They also treat static and mobile surveillance as the same skill and fail questions that turn on which method fits the objective.
What to do instead
Structure every surveillance answer as objective, lawful basis and location status, method selection, documentation plan, contingencies, and termination criteria. Practice choosing between static, mobile, and electronic methods for a stated objective, and articulate why the rejected methods were rejected.
Treating Pennsylvania's wiretap and electronic surveillance law as interchangeable with the federal framework, or assuming one-party consent resolves every recording question, without checking whether the communication is oral, wire, or electronic and which statute supplies the stricter rule.
One-party consent is a widely repeated shorthand, and candidates stop there. They also do not separate interception of communications from other conduct such as tracking, video recording, or accessing stored messages, each of which may be governed differently.
What to do instead
Build a comparison table with rows for oral, wire, and electronic communications and columns for federal and Pennsylvania rules, noting where Pennsylvania is stricter and what consent, notice, or authorization is required. Add separate rows for video without audio, GPS or location tracking, and stored communications. Then answer ten short scenarios using the table before checking.
Failing to identify and resolve a conflict of interest, such as investigating an opposing party in a matter where the investigator has a personal relationship, prior representation of that party, or a financial stake in the outcome, and proceeding because the client consented verbally.
Candidates treat conflicts as a legal-ethics concept belonging to lawyers, and they underestimate how often a conflict arises from prior work for an adverse party or from a family or business relationship. Verbal reassurance feels sufficient in the moment.
What to do instead
Adopt a standing intake checklist: who is the client, who are the adverse parties, have I or my firm had any prior contact with any of them, and do I have any personal or financial interest in the result. Practice writing a short documented conflict disclosure and a declination, since exam answers reward the documented step rather than the good intention.
Writing report and testimony answers that describe conclusions and opinions without the underlying factual observations, dates, times, and the distinction between what the investigator personally observed and what was learned secondhand.
Investigators are trained to deliver conclusions to clients, so candidates write like analysts rather than witnesses. They also blur hearsay and personal observation, which undermines both report quality and testimony credibility.
What to do instead
Practice rewriting conclusion sentences into observation sentences: replace 'subject appeared to be conducting a drug transaction' with the specific acts, times, distances, and conditions observed. Label every report statement as observed, reported by a named source, or inferred, and rehearse a direct-examination answer that stays inside personal knowledge.
Managing client communication reactively, giving verbal updates and opinions on the merits or legal strategy without written scope, interim reporting, or a clear boundary on what the investigator will not do, then discovering the client expected more or different work.
Candidates focus on fieldwork and treat client relations as common sense. They also drift into giving legal advice because clients ask, and they do not build the habit of documenting scope changes, which is where both ethical and contractual problems start.
What to do instead
Draft a model engagement summary covering objective, authorized methods, deliverables, reporting cadence, fee basis, and explicit exclusions including legal advice. Practice a scripted response for a client requesting legal strategy, and rehearse a scope-change conversation that ends with a written confirmation.
