It's hard to remotely judge how many of these flare ups involving violence occurred through the day, or whether most people were able to stand and peacefully assemble much of the time.

This was recently posted at youtube. I can't tell when bullets are being fired, but you can hear clicking noises at the beginning, which could be the pellets, and then some people are screaming out. This is on the west side of Wheeler.

By the same author - a group of police suddenly scuffles with a few students. I can't place where this is - on the other side of the building..

This could be near the above scene. A woman is being shoved after going through the bushes.

By the way, it looks like the Daily Cal was able to provide some of the best quality video journalism.
This shows the west side of Wheeler. There is an interesting moment of two students or staff trying to resist movement with bodyweight, but not using arms:
