@tulippetals- if the attacker had killed his first victim in a “personal dispute”, walked out of that property and stabbed two people walking past, who just so happened to be Jewish, then I’d say you might well be right that this wasn’t a racially motivated attack.
But after he stabbed his friend in South east London, he crossed London to North West London to go to a predominantly Jewish area and stabbed two people. He passed many other people in his distressed state, yet didn’t attack any of them, waiting until he’d found some obviously Jewish people before attacking.
