One month before the San Bernardino Massacre there was a jihadi knife attack at University California Merced. The media covered that one up as best they could. Luckily that jihadi was shot dead before he could stab anybody to death.
If knives are used, the media just doesn’t care! If a GUN is used by a muslim terrorist, the media just blames the NRA and the Second Amendment and simply CAN’T figure out why thy guy did what he did!!!/s
