You're missing the point, these are done by shooters who are citizens of the corresponding states, which subjects them to all of the regulations of that state.
With firearms(unlike almost any other product in the US), I can't just go to another state and buy a firearm. I have a to buy from a federally licensed dealer in my state which subjects me to all my state's restrictions. I can't side step the local regs buy buying out of state like say buying a car.
Most studies that have been done on gun control, even by those who can be considered as relatively unbiased.(i.e. places like the CDC), have shown that for all our laws. All of the gun legislation(I believe both pro and con) has made no statistically significant different in crime, either positive or negative.
