“Slow speed stupidity. Only in America can a person doing a good deed be arrested so easily. Perhaps the poor guy interrupted something he ought not have.”
The person who stopped the pursuit probably won’t get arrested or charged for interfering with a police activity. He will likely get a stiff warning about doing it again.
He didn’t interfere. He did the job they are too meek and PC to do. That it makes them look like idiots is a matter they should address to their gutless bosses.
