When the post-attack rally happened, THAT’s when he grabbed his camera and rode- about 6 PM, this was detailed on Vox news.
The evening after the shooting, Hogg says, he biked up to the school, where the media was still camped out. This time, he put himself in front of the camera, making his first — but not final — plea for an end to mass shootings. He made another on CNN on Thursday morning, calling on lawmakers to “get something done.”
Ah... But he says that when he rode his bike to the school that he did know that it was a mass shooting. See the problem with that? More than one day later and he still didn’t know?
And also he say in the CBS interview:
“On the day of the shooting”
Not on the day after.
