tell me again how "banning" worked to get drugs off the streets?
There is no logic to banning any weapon. We already have laws against murder -- if these killers were deterred by laws they would not have killed anyone. Banning only serves to disarm the innocent.
The second amendment is not about "having a useful purpose" for every type of weapon or attachment. It is based on the premise that an overbearing government would be deterred from removing our liberties. What you cretins call assault rifles were labeled so by idiots who know nothing about firearms.
Assault rifles (fully automatic, used by the military) are not available to civilians without special licenses already.
tell me more about how criminals always obey the laws. . .
the point is that these shooters are violent but they are not stupid to the point of possibly facing an armed response. There is no need to have an armed person at every moment/entrance. The deterrent is knowing that there may be someone carrying at any time.
If the teachers are trustworthy enough to take care of our kids; surely they are trustworthy enough to be armed to confront anyone attacking them.
