Jail isn't a great place. Breeds stronger criminals and whatnot. But to be honest? You might be over-thinking things here. It's good to know your rights and be prepared for an emergency, but there's also a line one must draw. Be prepared for most emergencies, know your rights and how to handle a situation, but don't let it dig into your daily life. Unless you're doing something pretty heavy(I'm thinking assault, theft, drug trafficking, abuse, arson, etc), you're not likely to go to jail. Even if you're suspected of something, it's pretty hard to actually throw you in prison.
