I mean, every action a police officer takes in any country parallels to some of the worst crimes imaginable. An armed person saying "You are not allowed to leave" is a felony in my country punishable by up to life imprisonment. While people argue about problems with police behavior or severity of criminal penalties, it is generally agreed upon that an arrest of a suspected violent offender is always worse than civilian kidnapping.

And perhaps outside of the police, for every person I've met who is so anti-cop they consider arresting even a serial-killer unacceptable, I have found common ground of some severe behavior they feel is only rightly done by the party trying to find a peaceful coexistance.
