1. Assault Weapon Ban would have meant that she could not have purchased an AR. Her intention was for maximum body count. But she was so inept that she could only bag 6. Had she been unable to purchase an "assault" style rifle, the body count may not have changed since she is so inept. But chances are, it would have been less. The ONLY handgun mass shooter in the last 20 years with a high body count was done by a Combat Marine. Imagine what he could have done with 3 ARs and a band of MAGs. Again, we are not out to stop the mass shootings, we are just out to make them harder to get a high body count and frequency.
Red Flag Laws certainly would have prevented this had her Mother and Doctor approached a Judge and had ALL her weapons seized and prevented her from purchasing any replacements.
The facts are, you love you AR more than you do children. Actually, your love of children may stem from needing more for target practice.
