Trickeration or It Ain't trickin' if ya got it
I have friends past and present in different areas of law enforcement and it is always fun to talk to them about different aspects of their job. One area I really enjoy quizzing them about is the investigative side. Especially their techniques in talking to people who are hostile and actively trying to lie about something. A favorite of theirs is when doing a street contact, like rolling up on a bum or suspicious person or whatever is to call them a fictitious name. Right off the bat. The person either agrees and you know they are instantly being deceptive or they protest they are not "fred johnson" or whatever name. The officer then goes on to insist they are indeed "fred johnson" and to also now start accusing them of some sort of petty crime. In the suspect's desire now to avoid being penalized in the name of someone else they often give up their real identity under this type of duress. And thus by your own means of deception initially you get to a truth ...
