Re: giving up personal passcodes
No. Don't deny everything. If you are caught in a lie it will go very very badly for you.
Police: Were you in Blackpool on the 13th July 2019?
Suspect: No
Police: Aha! Gotcha! We have CCTV of you there, and you used your credit card in a shop. So you were there. And you're lying to us, so you must have robbed the bank there!
Or the US version:
FBI: Were you in Washington on the 13th July 2019?
Suspect: No
Washington: Aha! Gotcha! We have CCTV of you there, and you used your credit card in a shop. So you were there. And you're lying to us. And lying to the FBI is a federal offence, you're under arrest and we're going to throw you in jail for a few years. We don't even care whether you robbed the bank or not, now we have you!
Or, even if you are telling the truth:
Police: Were you in Blackpool on the 13th July 2019?
Suspect: No. [The truth]
Police: Aha! Gotcha! We have a credible witness who used to know you who says they saw you there. So you were there. And you're lying to us, so you must have robbed the bank there!
Suspect: They must be mistaken! [The truth, they were mistaken]
Police: They are a respectable professional person, [True] you are a low-life bank robber, [False] the jury will believe them and not you! [True]
