Had Bina intended to assist in Oshie and Toews escaping, he would have been arrested and taken to jail where he would have had to post bond, and it definately would not have been a simple B-Misdemeanor. Escape, or Aiding and Abetting is at least an A-Misdemeanor charge, and most often a felony.
I have not seen anything that says any of the involved parties were arrested, just cited and released. If I'm wrong, please let me know.
