TexasRedneck,
NEWS FLASH: IF/WHEN everyone can LAWFULLY bear arms, that includes EVERYONE & we LEOs will NOT be able disarm the PREDATORS, UNTIL AFTER they commit a VIOLENT CRIME (IF THEN).
IOW, the fact that he shouldn't have been able to carry a gun, much less buy one, didn't stop him, did it? Which is exactly why the rest of society needs to wake up and be armed at all times.
