In the first clip, it appears the protester was not violating any law. The arrested protester is Black Lives Matter activist DeRay McKesson.

— Brandon Wall (@Walldo) July 10, 2016What is going on here is police taking out protest leaders.
I witnessed it personally during the Trayvon Martin protests in Oakland. The police would go into a crowd and go after a specific individual that they seem to have pre-identified.
Via a live stream of the 2012 NATO Summit in Chicago, I saw the same this tactic also used.
They know who they want.
