You have the RIGHT to bear arms.

Then you have the RESPONSIBILITY to make sure they are controlled.

Acts such as this are utterly inevitable in a 'gun culture'. Can all the outrage, you have the society you allow. Politicians will bluster but won't take on the NRA et al. It's probably too late to control HOW firearms are used already, there are too many out there.

Rights can be a real bitch at times . . . .
