Nothing prior to the invasion matters. If somebody decides to invade your home and start killing people does it matter if you ran your leaf blower while they were eating dinner two weeks earlier?
Does it matter what Darrell Brooks experienced in the ten years before he decided to drive through a Christmas parade? If people in Waukesha did not treat him the way he wanted to be treated, or did not support his preferred presidential candidate, or maybe even evicted him from his home is that a justification for his attack on the parade?
