Quick: Among all America's 20,000 overlapping "gun control" laws, which had an impact on the number of deaths when Islamic terrorist Omar Mir Seddique Mateen -– the wife-beating, ISIS-supporting, bi-sexual son of politically active Afghan immigrants -– went on a rampage with a couple of semi-automatic weapons in a gay nightclub in Orlando, Florida, June 12?

The "background checks" required by the 1993 "Brady Bill"?

Those didn't stop Mateen, a security guard, from buying the two semi-automatic, one-shot-per-trigger-pull firearms he used to murder 49 innocent Americans and wound 50 more.

Mateen had been investigated twice by the FBI — first in 2013 after he made "inflammatory comments to co-workers alleging possible ties to terrorists," and again in 2014, when agents examined possible ties connecting Mateen to Moner Mohammad Abusalha, the first "American" Muslim to carry out a suicide attack in Syria. Both men lived in Fort Pierce, Florida.
