Scientifically, when you have a hypothesis, you first try to replicate that finding (run an experiment, look for similar/identical results in other cases, etc.).
Then, you look for cases that contradict your hypothesis -- i.e. look for evidence that disproves it.
When it comes to gun laws, there have been many studies that concluded gun laws have little to no effect on gun-related crime. More specifically, states like Hawaii which tout a low level of gun violence due to our strict gun laws have been contradicted, because other states with much more lenient gun laws have the same or better gun crime rates.
Are these exceptions to the "rule?" The number of locations with Constitutional Carry, no permits to acquire, no handgun or long gun registration and no state-level background checks which also have low gun crime rates are many.
Evidence proves laws do nothing to stop crime -- gun crimes in particular. In Australia, after the massacre that prompted a nationwide confiscation/gun buy-back, there were more people charged with gun crimes than before. Most of those arrests were for violating the new ban/restrictions. All the law did was create criminals of the thousands of law abiding owners who opted out of a ban. Gun violence before and after the ban remained the same. The massacre was the exception -- a spike on the graph that no law would have prevented.
