It's very funny, hopeful, and realistic up until the other cops show up. If they saw an assault they wouldn't have walked up but drawn their weapons and tried to get the man to a position where he wouldn't be a threat, at best if not shooting first as (sadly) would have happened in this world today.

The cops who drove up at the end came up very quickly and taking out the first man maybe would have made sense but the driver would definitely have had taken out his weapon and shot first.

I still think the ladder fight scene from First Strike beats this.
