Crime in Walnut Creek? Boy oh boy, things have really changed since I lived in S.F. This sort of behavior is related to the society we live in, which is why I fled from Albuquerque. Punishment after the crime's committed is like closing the barn door after the cow has already escaped. We could always send criminals to an island, but I believe this is how Australia came to exist! It ain't working anyway. This is just due to people not being raised right. Mass media is culpable here as well. It's more powerful than we like to imagine, which is why corporations spend billions of dollars a year on advertising. They wouldn't do it unless it worked, and it does.
Violence and repetitious crime are why I had to get rid of my TV. The amount of cruelty, violence and aberrated behavior on there is beyond belief. Cop shows, news programs, movies about serial killers, gun violence, we are bombarded w/ it at every opportunity, even on commercials. And of course our brains react to it almost as if it were really happening, which is why we cry over a sad story and feel good when the hero wins. Watch Videodrome sometime. That's a sci film that's obviously fiction, but the premise itself asks questions about how powerful images can change our lives in the not-so-distant future.
Unfortunately, I don't think anyone can be helped out of addiction (experience w/ this myself). It always comes down to an individual making a decision to stop using, and figuring out a way that works for them. But getting factual information about how addiction works and changes our brains, not just drug addiction but all addictions, can empower someone. The better we understand the physiological reasons, the more knowledge we have, then the likelier we are to make better decisions in our lives.
