Well, they had assassinated yet "a few" (hundreds of) physicians, and nurses, and ambulance drivers in the area, so maybe are getting more bold about it.
> why not just make it to look like Hamas killed the aid workers?
Because they simply don't care, obviously. They even feel safe enough to film their own crimes.
The WCK withdrew from Gaza after being killed by Israel.
Now Israel can say that they didn't stop aid, they just "accidentally" killed an entire envoy of aid, which unfortunately led to the WCK withdrawing from Gaza.
So again, why not make it look like it was Hamas who killed the aid workers? I mean if it was all planned ahead seems like an obvious thing to do given that it wouldn't taint the "good behaviour" while also stopping aid.
