If you saw a crime being committed, any kind of crime, would you keep filming it on your phone or would you call 911?

Apparently a lot of people are more interested in filming someone getting beaten up, and other crimes than calling 911 for help! In George Floyd's case it paid off because the whole incident was on video and that's what won his case.
But don't you think we should call 911 too?
This question was inspired by another question asked by Liam.
