Add we can:
Baton:
-Is attached to the holster, with the striking end pointed upwards, while the handle section is pointed down.
-Holster will not be elaborate, but rather, a simple yet secure design.
-Chrome finished or shining objects of any sorts will not be present on either baton or holster.
-Holster is located at the very end of the rear belt section, where the front belt section meets.
Also to answer the question why the baton would have a cubic striking section to begin with, I believe it shares a similar design to the Imperial Ground Crew wands, which have rectangular sections, with a spherical handle, like the baton. However, this design for a riot baton still is beyond me, maybe if someone has a blu-ray HD shot of this scene, and could brighten the shot?
