Because your analogy is terrible.

It's more like saying that one dude in your friend group from when you were in your twenties always tried to get in fights whenever you went out went on to murder someone one day without you being there or around. You're now also blamed for the murder because you ran with him.

Or even better, your older scumbag sibling murdered someone, or parent.

The vast majority of these people aren't even working together. They barely know who each other are in large departments.

They also have one of the strongest unions in the USA coupled with institutional laws that protect them by default with little statistical tracking.

Those aren't issues where you blame people through proxy lol.
