So posting evidence and fact is "jumping on the bandwagon" but if anyone posts opinion than that's just discountable because it isn't evidence or facts...
I have big issues with this. UNRWA admitted that they have employees in Hamas, which they consider okay as long as they aren't miltants. However, many countries have declared Hamas a terrorist organization which creates a whole 'nother debate about funding UNRWA.
It's not out of line to think the footage could be of miltants and weapons. It's not the first time terrorists have hid behind the guise of just being part of the "political" portion of a miltant party.
