So the official narrative is that the Israeli security forces were senselessly beating the pall bearers.

But the reality is those weren't actually the pall bearers. That was a mob that had decided to take the body to parade it around the city, and what you see is a ill-fated attempt by security forces to retrieve the body. I mean you can argue it was still unnecessary use of force, and they should have just let the mob take the body; but unlike the MSM lets at least try to get the facts right.
