Via Powerline, the answer for those asking how Thursday's shooter was allowed to get a gun.
The system - already in place - failed.
Liberals are constantly proposing legislation to extend NICS to firearms transactions that don’t involve licensed dealers. As I have written repeatedly, the major problem with NICS is not that it doesn’t cover transactions between relatives, etc., but rather that the database is deficient. All mass shooters (I am not including terrorists here) are more or less crazy, but the vast majority are not in the database. So the exercise becomes futile, as it was here.
