Also where there are heavy controls on firearms, you see criminals with PISTOLS commiting the most gun offenses that injure and kill people. Baseball bats are also regularly used as well as knives. For the most part so called "assault rifles" are not used almost ever in any gun shootings. Infact, using those types of rounds of ammunition to kill someone is not as effective as a pistol is. Hollow point bullets are designed to expand like a pancake insdie of someone. "assault rifles" us bullets that penetrate people and go through them making a small hole. If you really wanted to commit mass murder, using a glock 9mm with a 100 round drum would be way more effective and easier to maneuver with than using an "assault rifle".
