The right to bear arms is a constitutionally protected right--in case this nitwit professor didn't know. has he ever read the constitution? highly unlikely. It would be just as irrational to say "I want the head of the NEA on a stick" for allowing this killer into the school. And it would be far more rational to demand every teacher, or at least every principal and staff members to be armed--that would have prevented the killings--more gun control will not. And controlling assault weapons? This guy used pistols, sorry the logic escapes me.
