Is it legal to have a loaded rifle in your vehicle?

just kinda wanted to see what any LE thought

ORLY?

A sheriffs deputy(actually 2) told me it was illegal to have a silencer

I think you answered your own question. When I want a definitive answer to a question involving law I don't ask a LEO. They can't possibly know all the laws they're tasked with enforcing. Sadly, this is the reality that the people making all these laws don't realize.
