The idf says it's real. You're trying to pretend that means its a fake, and if it is real it's a good thing because the palestinians would have killed the kids in a fake video...
And dealing with a real event and a real video... that's no demonization. That's dealing with reality.
English is not your first language is it, The IDF always admit to being at fault initially, then do a thorough investigation before releasing the details. In this case the fake uniforms are obvious, and why would IDF troops use cell phones to video the event. Another giveaway is the lighting that was on way before the troops entered the room, and the cameraman was already in place so he could film it all. Now that is dealing with reality not glossing over the facts and hoping that no one will notice.
And yes the Palestinians are known for shooting children after all they shot many last year when they were digging the tunnels for them.
