Last night, The Daily Show with Trevor Noah tried to test the theory that mass shootings can be stopped by just "one good guy with a gun" (as the NRA likes to put on t-shirts). They did this by making correspondent Jordan Klepper get a concealed weapons permit. They then tested his ability to take down a shooter by putting him in a law enforcement-approved school shooting simulation. Klepper—who now has a concealed weapons permit that's valid in thirty states!—didn't do so hot. In fact, he ended up accidentally shooting a civilian and was mistaken as the "bad guy" by law enforcement.
