It would take a second for a strong man to kill
a weak person with bare hands. (Would you prohibit
strong hands as a visible threat?] Without a weak
person having a gun, they are at a mercy of any
criminal, and have no deterrent.
As for mass murders, one can just drive a car into a
crowd. Now, how many people die from mass murderers?
And how many people die from eating unhealthy food
from MacDonalds, smoking, including secondary, etc.?
Bearing guns is a constitutional right, and mass murders
are probably the case of deaths number one thousand
something. Why not take care of the top of the list
of deaths first, especially when it doesn't violate
anybody's constitutional rights? Just because mass
murders sound more dangerous and look more photogenic?
