I'm not going to read through this whole thread, so forgive me if I touch on stuff already discussed in length.
I know a bit about weaponry, although admittedly not nearly as much I used to. In the 1970s, I rose in the ranks to the position of Infantry Weapons Platoon Sergeant. I was in charge of training troops in the use of M-16s, M60 machine guns, and mortars. When it came time, it was my job to assign gun and mortar teams out to infantry platoons in our company, lay out fields of fire, make sure weapons were clean and operational, etc. When my 4 years in the Marine Corps was up, I never touched another gun until recently when I bought a farm, after discovering the need to protect my livestock and protection dogs from predators.
In the Corps, I showed an aptitude for weaponry, firing high expert with the 45, M-16, M-14, and the M-60, all. I apparently retain some of that ability, given my success with predators.
I remember in the Marines dropping by a gun store to humor a friend and was surprised to see an AR-15. It looked exactly like an M-16. I broke it down and the only difference I could find was the ability to switch back and forth to automatic fire, although this was very superficial. I could see that a simple modification could easily remedy that difference. I was shocked to learn guns like this were available to civilians. I believed then and believe now there is no good or rational reason for this. People just don't need guns like this. These are guns of war, not toys or home protection devices. Nobody here or elsewhere will convince me otherwise.
I am encouraged that there are signs the gun lobby is losing its grip, both on the electorate and on reality. Wayne Lapiere used to be gun control's worst enemy. After his moronic, tone deaf comments the other day, he is turning into its greatest asset. The more these people talk, the dumber they sound.
