Had to read the post twice to fully digest your point of argument. Truly, they can stop people from owning a gun but cant stop people from committing crime. Self defense is the only way one can protect him/herself or use it as delay tactics before the authority comes to rescue the day. The guns are already out, it is not possible to take out all the guns.
One thing we all should know:
Guns don't kill people, People kill people.
If u support gun control, how do you then defend yourself when an attacker comes with other weapons like knife, axe or even bottle.
Yes, classic motto about the root of the issue: people and lack of moral understanding, despite the existence of a too that is made to harm other beings.
