To the OP do you open carry?(I open carry so im not saying u shouldnt) Maybe they saw you while you were out somewhere maybe?
Maybe someone called about a man with a gun and the stop was to look for your gun and not because of a signal.
Heres a question about telling the officer no I dont have a gun.
Wouldnt that be false informing or something and then his partner comes up on the pass side and says hes got a gun and then they are .
Im sure there is some charge they could stick you with if that happend.
The only time lying to the police is unlawful is making an official statement to the police. If you are just talking on the side of the road, and again IANAL, lying to the police is perfectly fine. If you are on the way to a ballet dance, and a LEO asks where you are going, and you are for whatever reason ashamed of going to the ballet, and you say you are going to a football game. Well then that is lying to the police, have you broken any law. Also by conversing with the police you are opening yourself up to scrutiny by the police. You say you are going to a game, well then they ask you about where the game is who is playing, etc... then they will converse a little more to make sure of your story... well it just opens up a whole can of worms when you tell the police ANYTHING more than what is specifically necessary for them to give you your ticket.
