Yes, that statement was made after he heard about Phil Hartman’s death, which occurred in ‘98. Don’t know where he stands today, but as I mentioned, he is a Hollywood Republican who gives no apologies for his love of country.
He must have heard about Hartman's death two months before Hartman's death, because that's when he said this:
"...until America, door to door, takes every handgun, this is what you're gonna have... It really is pathetic... We're livin' in the Dark Ages over there." Sylvester Stallone, March 28, 1998
