"...it was just another situation with two prickly men who got ticked off at each other and got unreasonable with each other."

Probably true enough - but there is a big big difference between what they did. Gettig angry and shouting a bit is in no way equivalent to arresting someone, handcuffing them and taking off to be locked in a cell when they have not done anyting that warrants that. Police officers are given special power, and they have a duty not to misuse that power which they exercise on behalf of the wider community.

Suggesting that both parties are equally responsible just because boity are at fault is analogous to saying that in a domestic dispute the one who uses violence is no more responsible than the one who said something that provoked that violence.
