> Anarchists can arrest people?
Anarchists have a concept called "unarresting" which is something done during demos and protests. It usually works best when a few cops have arrested somebody and the crowd outnumbers them. A tug-of-war between protesters and cops is initiated by quick-thinking anarchists. Most police usually expect nobody to come to the aid of the person being kidnapped, so the element of surprise can sometimes free the person(s) from the arresting officers.
