A long time reader posed this interesting question because it happened to her last week. She readily admits that she was guilty of the crime, a misdeameanor, but the police officer lied to entrap her.
The question she asked was, can they lie? Don't they have laws against such practices? What about their oath to be honest?
The answer might surprise many of you! A police officer is permitted to say almost anything to prove you are guilty of a crime. It's unethical, but lawful. Many courts have ruled in favor of officers that "fabricated" a story or lie to get a confession from a so-called suspect.
An example often practiced:
Two suspects arrested, brought to jail, separated in different cells. Detective John speaks to suspect A, tells him suspect B just "confessed" to him that "both" were involved in a crime. Suspect A, who originally stated he was not involved, now changes story and confessed, and through that confession implicates both of them.. Detective now has evidence to charged both with crime, though he lied to get it!
Lesson: This is why I tell all, and all attorneys echo this advice as well, shut your mouth and demand representation! A police officer is not lawfully obligated to assist you to prove your innocence at any time.
Please forgive me if I sound harsh by making this statement:
Police officers very careers, promotions, mortgages, their kid's college tuitions, their food bills, electric bills, car notes, vacations, and many other bills are paid by their arrests of YOU and I, or anyone suspected of a crime. He is not concern with your problems, your children, your bills, etc. Do you get it? This is their job! Also, they do not decide your GUILT, so don't think you can "explain" your way out of trouble. The proper venue for that is at court! Shut your mouth, period!
Now since I cooled down a bit, let me say another thing. Don't ever, under any circumstances, volunteer anything, unless you are a witness to a crime. The reason why I don't have an issue with this exception is because we all must perform our civic duties. But the constitution "gives' us all a right not to incriminate ourselves while a party to anything. So the first law, " PROTECT YOU FIRST, PERIOD"!
