It may be too late to listen in. Unless you happen to be listening to the mall security when and incident happens, comms may be very limited after the fact. I also heard it as Breaking News on CFTO, but since I wasn't listening to the scanner, I didn't bother running to it to turn it on. Precious listening minutes are lost from the time it happens to the time it made it on the news. If they are setting up a perimeter to catch suspect(s) or traffic points for an emergency run by ambulance, over the air comms are probably reduced to verbal communications by officers at the scene.
What should I program into my scanner in case something happens ?
I'm always trying to answer that question. We all have police/fire/amb in our radios, but there are a lot of other stuff that still use conventional freqs and a lot of other stuff that is moving onto trunked systems. That's what make our hobby frustrating (because we can't figure out a certain user) and fun (cuz we just figured out who that company is).
This is what came up
http://sd.ic.gc.ca/pls/eng_alpha/we... TOWN CENTRE &admin_do=42&company_cd=80051175 If these freqs are in use, it is not known by who: management, janitor, groundskeepers or security, which may even be an outside company.
