Except it happened at a BLM protest. And in this day and age, evidently having someone commit some violent act at an event is enough to blame scores (and more) of other people at that event, and organizations associated with it. And then de-platform them, and de-monetize them, .... and generally de-humanize them. (Like the protest at the Capitol)
Also, he was a member of the New Black Panther Party:
> NBPP head Quanell X said after the shooting that Johnson had been a member of the NBPP's Houston chapter for about six months, several years before.
> Following the shooting, a national NBPP leader distanced the group from Johnson, saying that he "was not a member of" the party.
But of course, any organization with ties to him would want to cut those ties and disavow him, making themselves look clean. Do you think BLM or other organizations would want ties to such people exposed?
