They are encrypted. One non encrypted channel you can listen to and here some of what goes on off campus is BPD Channel 5, 460.500 DPL 351. They respond to a lot of off campus incidents. At this time of year BPD has at least two units designated at BC Gang Cars.
EMS is, or at least was last year, provided by Armstrong Ambulance. Dispatch is via cell phone from BC PD. I don't think that the Armstrong units have BC radios. BC also does, or did, BU. How often or if those contracts are re bid, I don't know.
