The activists have been arrested for participating in similar protests before and a court has deemed that they were likely to participate in similar protests again, and cause significant public disturbances. Others have pointed out that the state police law that these arrests are based on are very controversial and are currently challenged in court. I might add that the judiciary in Bavaria has a very pro-prosecution reputation in cases against progressive activists.
