The guy was allowed to enter the street as it was the end of the event and cars were coming in to pack up. He reportedly bumped one person with the side of his car at a relatively low speed and then suddenly hit the accelerator hard and went straight into the crowd. Video of him being held by people waiting for the police to arrive shows him looking like he's also in shock and he apologizes for what he did. The guy's brother was also murdered (not by a Filipino) and then his mom attempted suicide in recent years and he's had a bunch of mental health issues and run ins with police, but seems to have no criminal record. I have no idea what was going on in his head. I don't understand why he did what he did. It's an awful thing to do. It just doesn't seem like a terrorist attack.
