Criminal and Civil Law Foundations Relevant to Security Work
Two systems, two consequences
Criminal law addresses offences against society, prosecuted by the Crown, with proof beyond a reasonable doubt and penalties such as fines or imprisonment. Civil law addresses disputes between parties, proven on a balance of probabilities, with remedies such as damages or injunctions. A single act can trigger both: a guard who uses excessive force may face a criminal charge and a civil lawsuit for battery or negligence.
Concepts to know
Understand actus reus (the prohibited act) and mens rea (the guilty state of mind), and that some offences are intent-based while others are negligence-based. Know the difference between summary and indictable offences at a general level, and the idea that ignorance of the law is no defence. For civil liability, focus on negligence (duty, breach, causation, damages), false imprisonment, assault and battery, defamation, and trespass. Vicarious liability means an employer can be liable for an employee's acts in the course of employment.
Evidence basics
Know the difference between observation and inference, the value of contemporaneous notes, chain of custody for items, and the rule that hearsay is generally inadmissible but may be noted for context. Guards collect information; courts weigh it.
Traps
Exams love "beyond a reasonable doubt" versus "balance of probabilities" swaps, and answers implying a guard can decide guilt. Another trap is assuming criminal acquittal bars a civil claim - it does not, because the standards differ.
Rule of thumb
Criminal = state versus person, high standard, punishment. Civil = person versus person, lower standard, compensation. Write notes as if both will read them.
