Illegally blocking? If that were illegal, why do the many police officers in this video allow it?
Those are 2 different videos, both taken at different times of the day. In your video link it's totally overcast, in fact the streets/sidewalks appear damp from a fresh shower.
In link #106 when the incident actually occurred it's dry, bright and sunny, casting clear shadows on the ground.
You have no idea any cops were there at the time of the incident. Zip, none.
I'm surprised you're still hanging around making comments without thought.
