Representative Honda (Democrat, California) has introduced H.R.378, the so-called Responsible Body Armor Possession Act (click to view the full text).
This bill is restricts the sale of armor Type III and higher (see the NIJ’s PDF outlining the rating system referenced by the bill) to approved groups like law enforcement and imposes potential penalties like a fine, up to 10 years in prison, or both on those who violate its terms.
This is, of course, utter nonsense and holds no real public safety value. In fact, it stands to endanger more people than it ever protects. It is hard to wrap your mind around how backwards the idea of restricting the sale of safety equipment to protect people really is.
Start contacting your Representatives now. The House of Representatives website makes it easy. Tell them you intend to make you own health and safety decisions and that will responsibly possess body armor as you see fit.
