You have to be joking right now with these links?
First one is a 56 second TikTok video with no credible reporting attached to it. Just the bald statements of someone in social media and some video clips that do not show any gunfire whatsoever. Hardly proves the kid was intentionally sniped. Is this what you accept as credible evidence of something? Also, like, Al Jazeera? Qatari state media with no credibility when it comes to Gaza. They followed none of the usual standards of journalistic integrity. Very clear state sponsored agenda. Obviously they are exaggerating and serving up the most scandalous, unverified "reports" and portraying them as fact. Next.
Second link, another Al Jazeera, this one is a third hand report that does not have anything to do with your claim that Israel is sniping kids. Even giving you an assumption that every fact alleged is true, at best it shows that the IDF shot a car that happened to have a kid in it. Obviously there are cars all over the place in Gaza, and so the IDF clearly isn't just going in and lighting up any car that they see. Perhaps this car was driving toward the tank that shot it? It is not proof that Israel knowingly targeting a kid, and it has nothing to do with snipers.
Third link, MEMo this time, also Qatari state media, a 15 second clip with a bald allegation that the kid's hand got shot by a sniper. Nothing in this link doesn't prove that the claim isn't entirely made up by Qatari State media and slapped onto a 15 second clip of a kid with a blurred out hand. You really accept that as proof that the IDF intentionally sniped this kid? How can the kid or the doctor or anyone seeing this know it was sniper fire and not a ricochet, or a piece of shrapnel and not even a bullet?
Fourth link, now jumping over to Egyptian state media. Still liars but with different motives. At least in this one they concede the kid was trespassing in a secured military area. The description doesn't sound like sniper fire though, sounds like automatic rifles. That's a far stretch from lining up right on a kid and blasting for no reason.
Fifth one, sounds legit even after sorting through the the extra innuendo and looking at the reported facts. Should be investigated. The tenor of your allegation is that Israeli snipers are literally just out plinking kids. This kid was on top of a building near a firefight and an active special forces raid, watching it go down. Maybe they thought he had a weapon or was acting as a spotter. If the special forces, trained sniper plinked a kid without following rules of engagement, the sniper should spend the rest of their life in a military prison. But I think Netanyahu is like Trump, promotes people who would let this guy off, like that sniper Trump pardoned
That's all the time I have right now.
