I mean the NYT has the videos and very clearly shows that he acted defensively each time. I was surprised by how clearly they were willing to show that considering their bias, I didn’t really read the content around the video, but that alone was interesting. Of course the title at the time made it sound like he was guilty so...
Followup reporting indicates that he was not asked to guard the business that he was "protecting", that the business asked him and others not to get involved and they did anyway, and that he instigated the altercation with the men chasing him in the video.
Here's an interview with a reporter who was on scene and rendered aid to the first victim. He gives a minute by minute recount of what happened from his perspective.
The instigation that led to the second set of altercations isn't entirely clear.
