that areas that have heavily armed law-abiding citizens have the lowest crime in the country.
this is a self evident, definitive statement.
it's the same as saying, areas that have heavily armed citizens that break the law have the highest crime rates.
or, areas with a high number of unarmed law abiding citizens have the lowest crime rates.
or how about, areas that have many law-abiding citizens have lower crime rates than areas that have many citizens that break the law.
a criminal is someone that is a non-law abiding citizen. The two are directly proportional to each other. less criminals = less crimes. more criminals = more crimes. No shit.
