An argument between former Milwaukee County Sheriff David Clarke and Dan Black while the two were on an airplane earlier this year culminated in a criminal civil rights case against the sheriff and an FBI warrant to search his emails.
Black sued, claiming he was unlawfully detained by six uniformed deputies and two K-9 dogs after a squabble with Clarke aboard an American Airlines flight in January.
Special Agent Jennifer Walkowski requested the search warrant for the FBI after being pointed towards the emails by Milwaukee County auditors.
One email from Clarke's personal account read:
“Sheriff has taken this asshole’s compliant under advisement and summarily determined that he can go to hell. The next time he or anyone else pulls this stunt they may get knocked out. Sheriff does not have to wait for some goof to assault him.”
Clarke had also made a Facebook post on the official Milwaukee County Sheriff's page regarding the incident, with a photo of Black and the following text:
“CHEER UP SNOWFLAKE… IF SHERIFF CLARKE WERE TO REALLY HARASS YOU, YOU WOULDN’T BE AROUND TO WHINE ABOUT IT.”
Inability to prove a civil rights violation resulted in the criminal case being closed in May, but a civil rights lawsuit is still pending.
Clarke, who has long been a controversial figure in terms of how he ran his jail, resigned from his post this past August.
