Elon Musk: It was jarring to see joy experienced by people that were killing civilians...babies

About the footage:
A 45-minute video compiled from body cameras of Hamas attackers, closed-circuit television footage, video from victims’ cellphones and first responders gives an unprecedented look into how events unfolded Oct. 7.
According to dw.com the footage also appears to show that the terrorists burned their victims bodies, with some images showing the disfigured faces of infants. Body camera footage worn by terrorists showed how they tracked down kibbutz residents and shot them dead.
The well-known video of German-Israeli Shani Louk lying lifelessly in the bed of a Hamas pickup truck as she is abducted from the festival grounds is also shown. In this particular recording, it's clear that the young woman is bleeding heavily from a head wound. It seems unlikely anyone could live for long with such a massive injury.
Then there is another image, one that is designed to provide perspective: 138 bodies lying scattered in and around a white party tent where participants were dancing before they were massacred. One-hundred thirty-eight dead, as the words on the screen convey — "less than 10% of the more than 1,400 people that Hamas terrorists murdered on October 7."
In one recording, a Hamas terrorist yells into his phone: "Mama, I killed more than 10. Mama, your boy is a hero." A reply can be heard: "Kill! Kill! Kill!"
Terrorists' cellphones also show video selfies of grinning, laughing young men — many well under 30 — as they celebrate in front of their victims corpses.
Asked how he would interpret the body camera recordings of Hamas terrorists, Ambassador Prosor said the Islamists wanted "to show what they did." Israel has declared war on Hamas, and this is a war of images, too. The more time that passes, said Prosor, "the more these images will be forgotten."
Images like that of the 6 and 8-year-old boys from the Be'eri kibbutz who see their father being shot dead and ask, "Why am I still alive?"

Elon Musk in 🇮🇱:
“It was troubling to see the joy experienced by the people that were killing innocent civilians, kids and babies… It's one thing if civilians die accidently, it's another thing to revel in the joy of killing civilians. That's evil.”
