Political correctness is a cancer. And perhaps the entity most debilitated by it is the FBI. Following the slaughter of 10 people at the King Soopers grocery store in Boulder, Colorado, we learned that the suspected assailant, Ahmad Al Aliwi Alissa, was previously known to the FBI because he was linked to another individual under investigation by the bureau. Itâs not the first time, and conservative columnist âSundanceâ reminds Americans just how many other mass shooters â most of whom were terrorists â were previously known by the agency. âThe FBI knew in advance the Pulse Nightclub shooter (Omar Mateen) and were tipped off by the local sheriff,â he writes. âThe FBI knew in advance the San Bernardino Terrorists (Tashfeen Malik). The FBI knew in advance the Boston Marathon Bombers (the Tsarnaev brothers) tipped off by Russians. The FBI knew in advance the Garland, Texas, shooters (Elton Simpson and Nadir Soofi). The FBI knew in advance of the Parkland High School shooter (Nikolas Cruz). The FBI knew in advance of the Fort Hood shooter (Nidal Hasan); and now the FBI knew in advance of Ahmad al-Aliwi Alissa.â
