Scary thought

Reading http://www.thebangswitch.com/its-not-about-safety-its-about-control-and-confiscation/ , it came to my mind that almost all gun control laws begin with control of “Military and Law Enforcement” type weapons. This would mean, in effect, all firearms chambered for “mil spec/LEO” rounds.

Am I alone in seeing this as reason for the .gov to keep switching calibers? Ban .38 Special, .357 Mag.,45ACP, 9x19, .40 cal and 10mm handguns? They're all traditional LEO rounds. And 5.56 and the virtual equivalent .223 Rem, as well as 7.62/.308, 30.06, .338 Lapua, .300 Win Mag and .50BMG?

Just spit-balling here, but there is historical precedent
