Um, the guy making the quote is not a member of the BLM. And, according to the Dallas Police Chief, BLM was engaging in peaceful protest. And, according to the Houston Police Chief, and the man pointing a gun at police officers was not a member of BLM.
Here you are, whining about double standards. Let me give you a double standard:
1) Black man in Houston points weapon at police. He is shot dead, and rightfully so.
2) White men at Cliven Bundy's ranch in Nevada point semi-automatic weapons at FBI officers, and they are not shot, but allowed to leave the area, and are arrested later. Had they been shot, Bundy and his followers would have been calling for a war against the United States of America..... Wait, they already WERE calling for a war against the United States of America.
3) In Oregon, a white man, Lavoy Finicum is killed after attempting to run a roadblock, then is shot while going for a gun. Right wing nuts claim he is murdered, and call for a revolt against the United States of America. These are the same right wing nuts who say that the black man in Houston deserved what he got, and that BLM is a terrorist organization, even when the Dallas Police Chief says it isn't. Want to know who the real terrorists are? The Dallas shooter, along with Cliven Bundy and his gang. No reason to separate them from each other, and say they are any different, unless you are a racist.
