I think many cops are bullies are get off on pushing people around. This seems to be more true of the younger guys those working in big cities, than of small-town cops and older cops. But there are good and bad in every group.
They enjoy their "authority", and they enjoy informing us peasants of it.
In this particular case, who knows? What is disturbing is to see many Americans saying he deserved to be falsely arrested.
BTW, while we're on the subject of cops and mistakes, here is a paragraph from the link I posted in #49.
Last week, he discovered that there were two versions of the same police tape: the one that was to be used as evidence in his trial had been edited at two spots, removing images that showed Mr. Dunlop behaving peacefully. When a volunteer film archivist found a more complete version of the tape and gave it to Mr. Dunlop's lawyer, prosecutors immediately dropped the charges and said that a technician had cut the material by mistake.
Do you think the technician's actions were a "mistake" or "deliberate and malicious"?
