This.
Of course we can suspect things. While I personally suspect that it's either a Muslim related attack against Christians or a BLM/Antifa related attack ("Rittenhouse
retaliation") against Caucasians, those details are still unknown at the moment and remain suspicions.
What IS known atm is that the perp (Darrell E. Brooks Jr.) is a 39 year old black male from Milwaukee who has a lengthy criminal record [including domestic abuse, battery, disorderly conduct, bail jumping, and resisting arrest] and just got out on a $1,000 cash bond a couple days before the incident occurred.
It is known that a black male intentionally targeted a group of white victims, and that the government/media will NOT like talking about this at all, as they only like to race bait in reverse. In this case, the media will defend the black perp and appeal to his "expression of frustration towards a systemically racist system". If, however, it was reversed and a white male intentionally targeted a group of black victims (say, at a Kwanza parade?), then you'd be hearing chants of "white supremacy" and there would be demonization of all white people.
Remember, the enemy is NOT "black people" or "white people". The enemy is THE MEDIA and their race-baiting, lies, and inciting of violence.
