I believe that being unarmed invites attack.
The inability (or unwillingness) to defend ones self seems to invite attack. Any defense course will suggest that "if you look like food, you'll be eaten". Act defenseless, and you'll be victimized.
That's nature at work. The weak are easy to feed on. Animals act the same in this respect-the weak get picked on until they die, leave or otherwise can't pass their genes on. It's healthy for the species.
Think back, to more a primal behavior, like elementary school, before our heads were clouded by preconceptions and propaganda.
Which kids got picked on, banged around a little, lost their dessert, etc.?
The bullies (well armed with attitude and physical strength)?
The little kids (unarmed by lack of strength)?
Or, the sissies (unarmed by their mother's telling them not to fight back)?
I daresay that among peers, the pecking (breeding) order is fairly well established by high school, when many begin breeding. I'm sure the young ladies are fighting over (there we go again) the sissy, hoping he'll father their offspring.
To accomodate any criminal activity by acquescing merely encourages the behavior by making it easier.
Why else would Florida's "shall issue" concealed weapons permit be so successful? Their violent crime rate dropped like a rock - it seems that nobody can pick out the safe victim, with all those people with the right to defend themselves.
How tragic for the felons, maybe they can get workman's comp if they take a hit. If the liberals keep on, don't be surprised.
When deprived of food (victims), an organism (criminal) will perish. Unless they stop at my house first.[;)]
The liberal side is for big government, with the idea of making citizens entirely dependant on the govt.. Hence the gun/defense issue, the welfare issues, the homeschool issues, etc..
Oh yeah, I forgot to say that I don't have proof. (unless you wanted to look at states crime rates vs. their CCW policy)
