That is because gun control only makes head lines when a mass shooting or high profile case is involved.
My point is that placing these restrictions do not disarm the criminals who already have guns. You will still see people dying in drug and gang related deaths. You will still have the jilted lovers shoot their spouses. You will still have family members pull murder suicides. The legislation does not stop gun crime. It only ensures those who commit those crimes were at one point legally able to purchase a gun. It will still leave guns in the hands of criminals (although that number could decrease as guns are harder to come by, unless a black market for guns, like drugs exist)
