I did a search and was not able to find the post office incident for which I started the thread.
You guys are right... it seems like there are many public place videos.
Since sidewalk filming is mentioned in the thread I found a video in Beverly Hills that almost seems staged... I watched it and the police were professional in every way and a high end shop owner even invited the father and son in for conversation cameras rolling.
On the other hand some of the high end shops tried to control the sidewalks and called police...
I like the older couple towards the end walking hand in hand...
