I'll have to agree with Zaac here. After careful thought I can say this was not a jihadist murder. The guy was nuts. He shot those cops because they wore blue, not because of the skin color. They could've been black, for all his crazy mind cares.
However, his insanity, unreasonableness, and rage was fueled by all those rhetorics against cops and the current American justice system, plus what he perceived as a call to arms by the mob chanting for dead cops.
Mr. Sharpton, deBlasio, and everybody else who have been involved in either direct or indirect statements that attacked the police in recent times cannot escape their responsibility, try as they might.
Neither can the media.
The sympathizers of Al Sharpton are trying to dissociate him from that mob, by pointing to a video where Fox45 (DC) was apologizing about having edited that clip because the chant was different, and you could agree with them that they are being portrayed badly until you realize the chant at DC is not the same chant at New York.
But the shooter ?
He was nuts, and like everybody else who got their guns easily to murder indiscriminately, his folks, and the proper authorities, should've put him where he belonged: the mental institution.
