The second caveat is that you should probably get a lawyer if anyone from law enforcement wants to talk to you in any way that is more complicated than a speeding ticket. Similarly, don't sign any papers or agree to anything without a lawyer present. You aren't smarter than the people whose job it is (on paper) to enforce the law (even if in practice, many police officers in the US don't seem to know or care to enforce it). Things you might be able to "coax" out of an individual officer get thrown in the bin anyway and your statements will be read in the worst possible light if given half the chance. Your lawyer is paid to understand the law (and if they're any good, they'll do what they can to protect you). That advice goes double if it's any three letter agency.
