They also seemed to be tolerating him waving the gun and acting insane up unto the point they didn't. It would be informative to know why the shooting started at that moment.
Did one cop just decide enough is enough and opened fire, did the guy say something, did he point the gun at them?
I think what changed is that he got near some cars with people in them. You can see him getting near one in a couple of frames of the video.
Imagine a scenario where he got in the midst of them and started shooting at people and the cops. It would have put a number of civilians in immediate danger. I believe that the cops recognized that and weren't going to let it happen.
The choices were
1 - Hope that crazy guy would come to his senses and put the gun down
2 - Shoot crazy guy who appeared to be suicidal before he got to civilians
3 - Let crazy guy get near and potentially shoot civilians
I doubt that they actually wanted to shoot him, but weren't willing to risk anyone else getting hurt.
