The chief of police in Gilberton Borough, Pennsylvania (population 834), is under fire after posting a series of profanity-laced videos that insult liberals, Secretary of State John Kerry and former Speaker of the House Nancy Pelosi. And he is in no way apologetic for any of them.

Police Chief's offensive shirt

Chief Mark Kessler’s 14-year career as police chief is certainly being brought into question as complaints are piling up on both his YouTube account and the city’s website. What are so many complaining about?

The video that sparked an investigation into Chief Kessler is a brief one but manages to pack in plenty of comments that many have found offensive. In the clip, Kesseler drops the f-word numerous times and uses the derogatory term “libtards” while wearing a t-shirt with an offensive comment on it:

Chief Kessler followed up that video with another that was titled “Chief Mark Kessler, I’m Sorry For Hurt Feelings”:

The police leader is also on record expressing his dislike of the U.N. and Secretary of State John Kerry. In this clip, he is upset about Kerry’s stated intent to sign the UN arms treaty:

In another video, Chief Kessler (in uniform) is teaching a class on pistol safety. He uses a target with a clown image on it and refers to the image as “Nancy Pelosi with her gavel”:

Sheriff says this is Pelosi

The entire 10 minute video can be seen here:

As of Wednesday morning, Gilberton Mayor Mary Lou Hannon is apparently standing by the chief.

In a phone call with TheBlaze on Wednesday morning, Mayor Hannon said she still considers this to be a “free speech” issue. In a ringing endorsement, Hannon said, “If you were in trouble, he’s the kind of guy you would want by your side, protecting you. He’s a no-nonsense police officer.”

Still, the mayor said she will raise the issue of Kessler’s conduct at the next council meeting. An open meeting is slated for 7pm Thursday night (July 25). A local TV station reports that Mayor Hannon said, ”He did not do it on borough time, or in uniform. We have no conduct rules for what anyone does outside the borough.”

When confronted regarding Kessler’s above video that does show him in uniform, Hannon told us she was not familiar with it but would be reviewing it before Thursday night’s council meeting.

TheBlaze contacted the chief’s office, but Kessler is reportedly on vacation until Monday, July 29.

According to local media, Kessler also sits on the school board and has formed his own “militia.” We did check out Kessler’s personal website that promotes his own Constitutional Security Force (CSF). Anyone interested in becoming a member must pledge a loyalty oath. It reads:
