According to sentencing guidelines, any other person with no criminal history would, yes, receive a similar sentence.  However,  doubt not: the DA would have prosecuted this 'any other person with no criminal history' quite differently. How so?  Fourth-degree assault and official misconduct the only charges pursued.  Why wasn't he charged with violating {18 U.S. Code § 242} (https://www.law.cornell.edu/uscode/text/18/242)?  If you or I had committed the same crimes as this officer under same circumstances, only we being without title, professional courtesies extended to, or any other benefits enjoyed by law enforcement officers for being such, I have no doubt there would be more than just two charges levied.  Officers that break the very laws they've been entrusted to enforce are far too commonly shielded by the system they're sworn to uphold.
That said, it's good to see those who abuse power over those they've sworn to protect held accountable, shown they aren't above the law.
