Did you bother to read the article?
"According to Bituah Leumi, Israel’s national social security agency, of the 46 civilians that were killed in Kfar Aza, the youngest was 14 years old, meaning that no babies were killed at Kfar Aza."
And no, zaka members do not know what murder looks like. Because Israel implemented the Hannibal Directive and so many bodies were badly burned, literally hundreds of Hamas fighters were initially counted as Israeli victims.
So yes, it matters very much that there are problems with unverified stories that Zionists promote.
