I always see people commenting on stories like this with things like "how does anyone actually believe that/think anyone will believe that?"
Well, that's exactly the point. It's not about the death being convincingly accidental. It's very much about sending a message to others.
You don't eliminate the competition and agitators with the exact same method of execution for 30+ years (with a few false-flag apartment bombings thrown in for good measure) and expect to keep things covert.
The only way they could make it more obvious is the "he hogtied himself, ate a cyanide capsule, jumped out the window and shot himself twice in the back of the head on the way down" trope.
I once drove a decked out panto with a friend of mine around the downtown area, so imagine two pantos (fiat panda) all tricked out to look like something you would see in a hot wheels box or need for speed game, bombing around town, literally doing circles around other players.
Armored up so they would have to break out explosives to kill us, but since we weren't trying to hit anyone, or shoot anyone, just driving around and whenever someone was stopped just circle a few times and move on.
Within half an hour we had about 10 people in a Panto convoy doing the same thing with varying levels of success. Sometimes it looked like a well choreographed dance, but mostly it was a cluster fuck of cars trying not to hit each other as we vibe and cruise.
Then someone came in with a jet and ruined our fun.
