But think about that, in your average day, how many opportunities did you have to steal or otherwise break the law. I'm guessing, A LOT, and how many did you take advantage of? (I speculate, none, because your standard of living is such that it's not an attractive option to you).
For house burglary the way to deter opportunistic criminals is to harden down the house just a little bit. Lock doors, close windows.
Often drugs is the driving factor. I notice that out of 207 comments in this thread, only 4 including this one mention drugs.
