• That's a federal requirement, doubling down on state law would have no effect • Again, no effect. See: unconstitutional Illinois FOID act and Chicago crime rates • Would have no effect, it wasn't his gun • Would change the gun used, no effect on outcome • No effect, shooter fired less than 10 rounds, the commonly adhered to restriction • No effect, see: any other state with waiting periods and crime rates • No effect, long guns aren't considered concealable • No effect, he was determined and would have ignored that law. It's already illegal to shoot at random people • No effect, he was over 18 at the time • No effect as once again he'd ignore any law, gatherings like that especially with high profile targets tend to ban them locally anyway So, Shannon, seeing as how your laundry list of bullshit wouldn't have changed a single thing, why should we throw away the bill of rights?
