OK, see, now you've gone fully off the "criminal safety" deep end.
If the criminal is so scared, maybe he should try earning his money, rather than taking it by force?
I don't care about the criminals safety. Ok, a little bit then, but mostly the victims. Even a criminal should get the opportunity to better himself, and until he does we should try to mitigate the damage he does, and keep him away from society until we have given him the tools to coexist with it. That includes helping him find a way to earn his own money.
Great! Then let's give him an incentive to "go straight" on his own, namely, safety. Rather than keeping him away from society, why don't we offer him opportunities
within society to better his position without using violence?
