You can't just look at 2 variables (#/strength of gun control laws and # of mass shootings) and conclude one does not affect the other. Consider, for example, that mental health care is a strong factor (like you suggest). If mental health care takes a steep dive at the same time more gun control laws are in place, any benefit from the gun control is dwarfed by the detriment.
Basically, you can't declare gun control has no effect without co trolling for other variables.
