Where Are Undercover Methods Legitimate?
The established lawful uses: test purchases proving counterfeit or substituted goods; mystery customers measuring whether cash sales reach the till and service standards reach customers; observational verification of gate discipline, night operations and contractor reality; and integrity checks confirming suspected schemes, the bribe-demanding buyer, the fee-skimming counter. Each works because the operative merely does what any customer or employee could do, and documents it.
What Separates Investigation From Entrapment?
The controlling principle: observe and verify conduct that exists, never manufacture conduct that didn't. Offering a normal transaction that a corrupt employee exploits is evidence; engineering temptation designed to break someone who would not otherwise offend is entrapment, and it poisons proceedings and ethics alike. Professionals script operations so the subject's own initiative provides every incriminating act.
What Makes Undercover Evidence Usable?
Discipline in three layers:
- Scripting and authorisation: written scope, approved scenarios, defined no-go lines before anyone deploys
- Documentation: contemporaneous logs, receipts, sealed purchases and lawful recordings in permissible contexts
- Corroboration: undercover findings matched to records, the till data, CCTV and documents that turn one observation into proof
