I would put it to you that the genie came out of the bottle back in the 1970s. Up until that time, the industry was an “observe and report” industry, and large segments of it still are. However, observing and reporting just didn't cut it anymore. The police response was too slow. In many cases, when the police arrived, the situation was gone, the damage was done, and the aggrieved parties were frustrated. There was a great demand from the public for remediation, for some level of intervention and remediation in low-level crimes.
That's what the public is concerned about. It's interesting watching television about serial killers, because what we are all concerned about in our communities is being accosted by toughs on the street, drunk and disorderlies, and this sort of thing. Parking problems and parties are the big things.
So around about 1970 was when the massive hiring of private security and the large enclosure of public spaces into semi-private spaces—the closed shopping mall—started to take place. It was a moment of truth for public policing. They could have gone in and taken their writ inside these places—these transit organizations and the huge malls. They chose not to, so private security just grew up to take care of that. You cannot go back. You could never go back.
For most Canadians, their first experience of enforcement and authority is from a private, uniform-wearing guard. The great focus for private security is deterrence. The uniform being there cuts it 90% of the time. Hands-on intervention is required in very few cases, but when it is required, when there's a crime in progress, there is no time to just observe and report. There has to be an intervention, and that's why the industry is where it is now.
