Q: The police left a number for me to call and said they wanted to congratulate me for something and give me a gift. When I got there, they handcuffed me to a chair, processed me and gave me charges. (Pittsburgh, PA)
A: Much to the chagrin of unsuspecting Defendants out there, the police can use a degree of trickery to arrest, as long as that trickery does not violate due process and fairness. For example, they cannot use trickery to the extent that it causes someone who is not predisposed or inclined to commit a crime, to commit one. Your situation, yes, it is legal, unfortunately. Take your papers to an attorney. Perhaps you will have a defense and enjoy the last laugh.
