This Southern Poverty Law Center video was created to help law enforcement agencies better prepare for encounters with "sovereign citizens." In the case of two West Memphis, Ark., police officers, Brandon Paudert and Bill Evans, a routine traffic stop of father-and-son sovereign citizen duo Jerry and Joe Kane in May proved fatal when son Joe, 16, leaped from the car firing an AK-47, cutting down both officers. The Kanes died in a shootout with police an hour later in a Wal-Mart parking lot after wounding two more officers. SPLC estimates that as many as 300,000 people may consider themselves sovereign citizens — and the number is growing.
