If you are stupid enough to cheat on your girlfriend/wife, and they find out, they will then accuse or suspect you of cheating on them with all sorts of people that you are not cheating on them with. They will come bustling over every single time you are talking to any woman and start to act territorial.

Why?

Because you destroyed their trust. Once they realize something is possible, they start to try to see the pattern before it comes around to bite them in the butt. And yes, that means that they will jump at every little thing that is actually nothing, but that's because you made them jumpy.

Centralized government made us jumpy by doing all sorts of nefarious crap behind our backs. As we find out, it is only natural for us to distrust them and start to think that they are doing all sorts of things that they actually are not. That's how our minds work.

Buffalo Springfield from "For What It's Worth":

Paranoia strikes deep
Into your life it will creep
It starts when you're always afraid
Step out of line, the men come and take you away

Worth listening to for a minute:

Paranoia on the part of the community is part of the healing process. Whether leaders can regain our trust depends mostly on them, but some on us to make sure we are not over reacting.
