If you carefully reread what I wrote, it was, "...Ibragim Todashev's friend was partly to blame..." The point being that the hidden premise I was pointing out is that Tamerlan Tsarnaev was, in fact, one of the Boston Bombers. See how hard it is to spot?

That said, it's probably unnecessary to address the rest of your post, but I will due to its tone.

One does not cover up a shooting if the victim is responsible for a terrorist attack.

If it was a murder or due process was egregiously violated, of course they might cover it up.

Nobody in any of the communities...believes the narrative you are pushing...the title somehow gaslighting people into believing he was responsible for his own death, as it implies that he was a terrorist?

That's where you may have gotten the idea that I am acting in bad faith. That is not what I am trying to say at all. My conjecture is that the title is part of a psychological operation to instill the belief that Tamerlan Tsarnaev is guilty of being a "Boston Bomber."

Further, you can't know whether or not everybody in a community believes something, and even if your generalization were true that would be argumentum ad populum--the fallacy that something is true or false based on popular belief.

Your remaining questions don't seem serious.
