Legally, if a cop has a reason to talk to you, YOU DONT HAVE TO TALK BACK.
as they say, YOU have the right to remain silent.
theres nothing they can do if you do that, its your voice, they cant MAKE you speak.
Its ALWAYS best to be silent because they seem to feel the need to use ANY AND EVERYTHING you say ANYWHERE, and try to bring it in court and make it incriminating
