As time goes on, there will be no more safe cities?

My town has been known for its vast percentage of Mennonites and the churches on almost every corner. But as I get older, I see that despite all the bible-thumpers, gangs are growing in numbers. People are getting shot in their cars and in their homes during drive-by shootings. Most of the time, these shootings are in broad daylight. So Im just wondering as time goes on, and each small town changes into a booming city, will there be anywhere relatively safe to live...
