These answers are so simple if one just uses their mind unfettered by demigods.

Watching Greta the other night and I believe she is an anti gun person. Nonetheless, she had on some guy from the Phoenix ATF and they were at the range. The ATF was demonstrating how an AK 47 round cannot be stopped by a vest commonly worn by the police. The implication was only these “assault weapons” can do that. Of course there was no mention of the fact the vest demonstrated upon was the minimum protection vest, no additional inserts, and that police in normal police work, such as stopping cars, are not frequently fired upon from inside by perps armed with rifles.
They also demonstrated an M-60 firing. I cannot recall the last time, er make that ever saw, an M-60 for sale in a gun shop. The best story was the fact the ATF was not able to stop a 50 cal BMG from going over the border. That was when I turned the show off as they were showing the cans of belted 50 ammo they did seize. I wonder where the 50 came from? Oh, that was probably never mentioned.
