Again, that is not what happened. He went over time. He left the podium. He stopped and talked to the council. He was asked to leave. He refused. The police asked him to leave. At that point he made the decision to leave in handcuffs rather than in the normal fashion.

Asking him to leave sounds likely to be an abuse, but it's a far cry from "arresting a citizen for going 3 seconds over their allotted free speech time."
