If we're talking about automatic rifles, i. e. machine guns, then I doubt it. Criminals will sneak them across the US-Mexican border, as they do now. Remember, the M-16's issued to Mexican police often end up in drug cartel hands because of the low pay to the officers. The cartels offer them 300% to 400% pay raises, they take their issued rifles with them, and the cartels now have machine guns. Also remember that the US Dept. of State has been approving these machine-gun sales for decades. That right there is at a minimum a good chunk of the gun-controller claim about "90% of illegal guns in Mexico came from the USA". Whoops.Do you expect that will eventually work? After 20 years or so of such a policy will we actually live in an America where violent criminals won't be able to easily get an automatic rifle?
The other way is to smuggle in fully-automatic Kalashnikov rifles (AK-47, AK-74) from other countries.
From 100 to zero? I doubt that reduction as well, given that automatic rifles are already very highly restricted for legal private ownership, per the National Firearms Act of 1934.Right now, we typically have about 100 murders every year committed with automatic rifles. If your suggestion becomes a reality would that number drop to closer to zero?
Someone mentioned that those who personally own automatic rifles tend to have a background in the military forces and/or law enforcement. Is this really the case?
