Would stricter gun regulations decrease the number of violence crimes committed in the USA?

When the American Constitution was written and a part was included about the right to bear arms, the founders were envisaging those weapons that they had at the time. It's unlikely that they werre envisaging the need for people to wander around with assault rifles, which is how some like to exercise their Constitutional rights. Meanwhile in Canada, 22% of the population own a gun, compared to 36% in America. A 2012 report states that there were 8,813 gun killings that year in America. The Canadian figure was 172. America's population is around 9 times Canada's, but the rate of gun killings is more than 50 times.This could represent more accurate marksmanship by American citizens, but it's equally possible that reasons for the disparity are more complex. Even if a campaign against the gun lobby were to succeed in restricting access to certain gun and ammo types, there's nothing to demonstrate that such a move would reduce violent crimes overall. The desire to kill can be realised with any number of tools. A gun just makes it easier to act on impulse
