A prime example of why you should be required to pass rigorous training before you are allowed to buy a gun and ESPECIALLY before being issued any conceal and carry permit. We need to take classes and pass written and practical tests before getting a drivers license, why should it be easier to get a gun? (NOTE- people steal cars, drive underage and while drunk and yet we STILL require licenses to drive. So the argument that “Bad guys will get guns even if its illegal so why make it harder for the good guys to get guns” is kind of silly when you think about it..) Almost ALL of these people were professionally trained. Your average Joe with a gun would most likely have injured MORE people in the process of trying to bring down the shooter. Hell, even professionally trained cops hit innocent bystanders more than they’d like to admit, how do you think YOU would do under that sort of pressure?
