Hannity didn't have to claim, in several places you can see things being tossed in the video and around the one minute mark you can hear someone yell to stop throwing rocks, throw snow.
..also around the fourty second point you can hear glass breaking like either bottles were being thrown or a car window was broken.
No, at the one minute mark, he says to stop throwing snow, it does not say stop throwing rocks. He says, HEY stop throwing snow, people don’t throw any snow.
