Finding Our Spine: Interview with Activist Gavin SeimThe Liberty Brothers Radio Show One such individual is Gavin Seim. Gavin, as he states during the interview, found his spine at an illegal checkpoint in Texas. Gavin refused to show his ID, and subsequently blocked traffic for 15 minutes until he was released without producing a thing. The guy has guts, and sometimes guts is enough. I watched the first video linked below, and I knew right away that we needed to speak to Gavin on the radio. In the video, he pulls over a police officer and educates him on the illegality of his non-marked police patrol car. Rightfully, the video went viral and is a must-watch. In the video linked below, you can hear the full interview with Gavin recorded LIVE on The Liberty Brothers Radio Show.
