Several hundred bikers have protested outside a courthouse in Waco over the continued jailing of more than 100 bikers, friends and family members three weeks after a deadly shootout at a restaurant.

Bikers proclaimed their constitutional rights and held signs Sunday outside the McLennan County courthouse.

The protest was organized by the Dallas chapter of the Sons of Liberty motorcycle club. Bikers circled the jail and detention center twice before parking in front of the courthouse.

The Confederation of Clubs and Independents urged members in an email to avoid the protest so as not to "exacerbate what is already a highly charged" situation. That group is the one that organized the May 17 meeting at a roadside restaurant that ended in gunfire.

Nine people were killed and 18 injured.
