After receiving a speeding ticket on November 10, 2017, Riehl filmed seven YouTube videos where he "ranted" about the incident and likened the officer who issued the ticket to a Nazi. He also sent at least 18 emails to the LTPD and the issuing officer for the ticket to be dismissed. Riehl became the subject of an investigation which concluded that Riehl had not threatened anyone and therefore his actions were not criminal. On December 12, a 'Hazard Hit' was placed on his address, stating that there needed to be a "Minimum 2 Car Response" from police when attending.
