If someone beats me up, it would be absurd for me to think, "If I make myself weaker and more defenseless, he'll leave me alone."
Think about this: In Switzerland, each individual citizen in considered a member of the national military (or militia, if you will), and is provided with an assault rifle and a sidearm by the government. Their crime rate is near zero. The two have to be linked.
Also interesting is the punishment codes of Singapore, where the punishment for any particular crime is extremely more unpleasant than it is in the US. Their crime rate is also near zero.
Combine the two, and the cocky "Whatcha gonna do?" attitude thugs love so much disappears, and crime drops.
Also, banning guns will not result in criminals unable to do anything but yell "BANG!" Supposing that such a ban succeeds in removing all guns from the public (right!), the criminals will move on to knives. Ban knives, and they use rocks. At this point you have a 'good luck' situation.

Young men make wars, and the virtues of war are the virtues of young men: courage and hope for the future. Then old men make the peace, and the vices of old men are the vices of peace: mistrust and caution. It must be so.
