Heller-McDonald made it clear that firearms regulation was acceptable. Although, all the gun loons heard was "individual right" and their diseased minds went from there instead of seeing what was actually said.
Now, it seems that Bill O'Reilly is actually agreeing to reasonable regulation:
COSTAS: Roughly 40 percent of the guns purchased in this country do not require a background check for purchase.Didn't see that one coming did ya?
O'REILLY: Ok. So you want a background check, right?
COSTAS: You have that. You've talked about stricter penalties, harsher penalties for those --
O'REILLY: For criminals.
COSTAS: There is that. There ought to be training programs for those who purchase guns. I don't see any reason why someone should be able to purchase military-style artillery and body armor and automatic weapons. Only the police or the military should have that --
O'REILLY: All right, all of those are reasonable positions.
