A St. Paul police sergeant has been placed on administrative leave, Fox 9 News reports, after being accused of telling drivers, in a Facebook post, to run over Black Lives Matter protestors.

Anti-police brutality activist Andrew Henderson saw the comment, posted under the name “JM Roth” on Facebook, which he attributed to Sgt. Jeffrey M. Rothecker in an internal affairs complaint filed Sunday.

“I was just flabbergasted,” Henderson told the Minneapolis Star Tribune. “A law enforcement officer is supposed to serve and protect the people, not incite violence against them.”

Here is the comment:

Run them over. Keep traffic flowing and don’t slow down for any of these idiots who try and block the street. Here is the deal, you continue to drive and if you hit someone make sure you call 911 to report the accident and meet the cops a block or two away and you can justify stopping further away because you feared for your safety since the past people in this group has shown a propensity towards violence. Since they are trying to block the street and/or cross where there is no crossing you should not be charged with anything. Now, these idiots could try and sue you in civil court, but remember that it will be jury trial and so most likely it will come out in your favor.

The SPPD is investigating the post, St. Paul Mayor Chris Coleman said in a statement Monday. “If the allegation is true, we will take the strongest possible action allowed under law.”
