That's pretty routine in Indy to the point that who gets arrested, how long a group blocks an intersection, etc. is usually scripted ahead of time after it's negotiated out between the protest group and the city. I suspect it's part of the reason the civil unrest that hits similarly sized cities doesn't hit Indy as hard, combined with a "stand your ground" and very self-defense friendly prosecutor's office. Indy had some violence, much more then usual, but perhaps not as bad comparatively as much of the same sized population centers.
