Yeah, I was arrested when I was 18 and haven't been since. I can tell you to listen to the good bros and Rick Collins. If the police have you, cut and dry, they come and take you. If they talk to you, it's cause they don't have shit and want you to hang yourself by talking. And they have all these fun tricks but you only need to tell them your name, and show ID I think, then say I don't want to talk.....when they keep up ask them "am I under arrest?" Decline to talk, leave or ask them to please leave. Don't be a jerk but don't be nice. Be business like. A lot of people feel like this makes them look guilty. So what? You probably are, but they don't know that unless you tell them.
Anyway, I have been visited once since my arrest many years ago. I didn't answer and the USPS Inspector left a business card. I had my lawyer call him and say we don't want to talk to you.. He flipped on my lawyer and talked all tough... My lawyer said he has to get enough evidence to arrest me or pull me in to question me. The Fed was all talk.. He had nothing, and I never heard from him again.
Do not talk to them. If they have evidence then believe me they come and get you. If not, they will try to get you to hang yourself. Don't do it.
If you think you've done something that will allow the police to go to a judge and show probable cause to search and seize your residence then clean house until things blow over. If you're creative you can think of other places to store your valubles.
And for shit sake don't think talking/narcing will EVER help you... IT WILL NOT... THEY WILL SAY ANYTHING TO GET YOUR GUMS FLAPPING
