They never cared in the slightest about Officer Brian Sicknick. They had just spent months glorifying a protest movement whose core view is that police officers are inherently racist and abusive. He had just become their toy, to be played with and exploited in order to depict the January 6 protest as a murderous orgy carried out by savages so primitive and inhuman that they were willing to fatally bash in the skull of a helpless person or spray them with deadly gases until they choked to death on their own lung fluids.
He’s right of course. If you support BLM then you necessarily support the routine verbal abuse of police officers as racists akin to the Klan. So it was very curious that a police officer would suddenly become the hero of this same group of progressives apart from the politics of doing so. In fact, you may recall people were simultaneously claiming Sicknick was a victim of the mob and that the same Capitol Hill police had treated BLM protesters unfairly. He was both a victim (where needed) and a perpetrator.
