I hope your son's insurance covers this.
If a thief would work as hard at a real job as they do stealing,, they'd be miles ahead of things. But sadly, they often want the "quick buck" without actually being a responsible person. Steal something, and loaf until they find another item to steal.
Worthless O2 thieves. They should be seriously prosecuted when caught, so others might not want to be so inclined. Severe punishment has always been an effective deterrent to many who MIGHT have thought about committing a crime.
Not perfect,, but very effective.
Nowadays,, the lack of fear of prosecution etc causes a lot of thugs to say; "Hey, easy quick money & I ain't gonna get punished."
I grew up hearing stories about how a thief in Turkey, when caught, would get his dominant hand, (usually the right hand) cut off. That meant he had to eat and wipe with just one hand. Plus, it let the public know he was or had been a thief. I always thought about how effective that had to have been.
