In Texas, New Mexico and Arizona, dealers can sell an unlimited number of rifles to anyone with a driver’s license and a clean criminal record without reporting the sales to the government.
If sales were reported, then trends could be tracked. That might have stopped a Texas smuggling ring from transporting at least 339 assault weapons into Mexico in 18 months, one of which was used in the murder of four police there.
If you buy a car, your name gets reported to the government. The same should be true for guns. This isn’t a gun ban, just common sense, seems to me (and I support the right of citizens to own assault weapons.)
