The changes were small, people are scared and weak minded. You give up this freedom for a false sense or security. It's happening everywhere, America included. Plus, you should assume that it's not just this one city. Though crime is fairly minimal, and it's not likly people see the atrocities that have happned to their lives, after all, what harm is happening to them? They have jobs, food, personal lives (Within the acceptable use of the word, at least). They feel safe, and when sheep feel safe, they rarely move.
