Well sure, and I'm not a lawyer or your lawyer, this isn't legal advice, etc.
I'm pretty confident that I know who killed both of those people. I'm pretty confident that both did it for ideological reasons. I'm pretty confident that both of those ideological reasons would be seen as "left leaning" in the American political spectrum.
As you say, neither has been convicted, but fortunately I'm not a court of law so I don't have to wait until they are convicted to draw inferences from what I see in the world.
Leave aside the shooters themselves for a moment. The other thing I find interesting is how those events are discussed and understood by other people, especially in contrast to right-leaning violence (like the people who killed Alex Pretti and Renee Good, or the person who killed Melissa Hortman and her husband and also shot John Hoffman and his wife, or even the guy who killed Jonathan Joss). Generally I find it to be a mark of extremism if you feel that political violence is justified as long as it is done against the other side. I've spoken to a lot of people who I would characterize as left-leaning extremists because they outright support the killings of Charlie Kirk and Brian Thompson, even if they wouldn't do it themselves.
This is different from understanding how they could happen, or sympathizing with the killers. I'm talking about people who outright cheer for this to happen more frequently. IMO they do not understand what kind of world they are asking for, but that doesn't stop them from cheerfully asking for it.
And similarly, I've seen people who dismiss the killing of Renee Good or Alex Pretti as justified because she "weaponized their vehicle" (no she didn't - watch the video) or because he brought a firearm to a protest (so what - that's legal ... and what about Kyle Rittenhouse?)
So basically, lots of words to say ... violence against people for ideological reasons sucks and isn't justified. Don't do it.
