I have observed in my life that paranoia often leads to real reasons for paranoia. Once I was pulled over for speeding in Oklahoma at a very inconvenient time. I placed my things in my backpack in the back seat and even though I knew it was completely obvious, I didn't let the cop know how I felt.
Although I know nothing is absolute, I can at least recommend simply not acting as though you are doing something wrong. To me, illegal does not mean wrong. I am disgusted by written laws, spoken laws, physical laws, etc.
