C-GAOL is the Winnipeg Police helicopter. I have yet to confirm a sighting of it on my feed. We have just recently picked up 2 more feeders in the Winnipeg area and so now MLAT is starting to work. I'm hoping to 'see' it soon. A few weeks back, someone was told by a Wpg Police officer that the helicopter spoofs it location so it cannot be tracked. Truth/fiction?
That would be a bit foolhardy when other traffic rely on seeing where it is, the whole reason for having ADS-B in the first place. Fiction !!!
You can't spoof MLAT positions. It could be spoofing the ICAO hex id though. Wouldn't expect a police helicopter to spoof anything though.
