Using Riot Suppression tactics, you know how to pin targets quickly for capture.
Prerequisite(s): Shinsect Riot Style, Str 15 or Dex 15, Base Attack Bonus +3.
While in Shinsect Riot Style, you can perform a Takedown. Make either a grapple, trip or reposition combat maneuver as a full round action. Should you succeed at any of those maneuvers, you can immediately make a pin attempt as part of the maneuver (which is another grapple check). If you have a club, baton, tonfa and one free hand, you do not suffer the penalty of not having two hands free to grapple a creature.
Normal: Grappling a creature without having two hands free grants a -4 penalty to the grapple attempt.
