Circular force continuum. If he had immediately complied and been choked to death then they wouldn't have needed to beat him. I know some bleeding heart will probably post that he may have been mentally ill but EVERYBODY knows that you should submit to lawful actions by a police officer. People that are mentally ill just like to use their illness as an excuse. Now, all because of him, two officers with YEARS of service and more than likely commendations and such might lose their jobs over this.
If you cant submit someone without a taser you shouldnt be a cop. If you injure someone as a result of an arrest that should have never happened, you should lose your job.
