if i really have to provide a stance, i would say it is likely that the answer is not that simple. you can't just look at one varible to access the whole situation. there are bound to be other factors (might be much more significant than gun laws) that affect the crime rate. the situation might be more complicated than you think. even if you obtain a set of reliable data that tells you gun laws and crime rate are indeed causally related to each other, it is likely that the conclusion cannot be simply generalised to other countries due to the fudamental differences in the structure, economicsculture and so on.
thus, i remain neutral.
