I'm not familiar with the source, but of so, I'm going shopping. A ban on semi-autos seems like BS, but it would be a total shit storm if it were to get passed.
Frankly, it seems counter productive to add nation-wide initiatives for law enforcement at the federal level. That will add vast costs in a time when the nation nearly shut down. The country's economy was on he brink of collapse as it was, and they want to focus their attention on this?! It defies logic.
On the other hand, if it's just hype and it doesn't get passed, it'll jack up gun sales and further at least one faction of American business.
