None whatsoever, and I'll concede the argument. Now that my head is clear, I realize I actually don't care if anyone can demonstrate any basic ability with or safe handling of a firearm on the street, and I certainly don't feel the government has any responsibility to the public to make any effort to ensure they do. I do concede...I've seen no data to indicate that folks who've never handled or trained in the use of firearms are a danger to anyone when they use them. I've seen untrained people endanger themselves and others multiple times, of course, but have no data to support that, or to support the notion that training would have prevented the alleged endangerment. But in any case, the government certainly has no responsibility in this regard anyway, and of course its efforts to take responsibility would certainly fail because in general, the government is utterly incompetent in establishing legislation that solves any problems when it comes to firearms. Amazingly so, actually.
