Rick Moranis hasn’t been famous in decades. And given that he was attacked from behind, its unlikely the attacker knew him. Just some guy lashing out randomly for who even knows what reason.
I wonder how often this must happen to non-famous people that don’t make the news too.
NYC has one of the highest police budget’s per-capita in the world and Manhattan is one of the most densely surveilled places in the country. I have to assume if cops are too busy crushing candy on their phones, this sort of thing is regular and they don’t give a shit.
