Yes, the drug crims will still get their guns, but they do not go around shooting school children. When guns are controlled = you need license and guns are registered, those on black market become very expensive, and the small time criminals who just want to get one to rob you would not have that sort of money.
Also, when people do not have easy access to guns, less people die from suicide, while they may still try using other methods, not so many succeed.
To say that the bad media is blamed for people wanting regulation over guns, is just ridiculous. “The media” is not homogeneous entity; there are plenty for gun - FOX, Breitbart, Infowars, not to mention the Russian bots that flood the social media
The statistics are clear; more guns in society equals more gun death, and member of household that has guns has many times more chance to get shot than person who lives without guns.
We have strict gun control; that does not mean that people who shoot for sport or hunt, farmers and other people who need guns, cannot gets them. They just have to pass strict background checks. Most murders by gun are drug gang related. In America people who are on terrorist watch list are not allowed to get on a plane, but are able to buy a AR15; that is insanity.
