We can supply you with the names of people who have been killed, of the officer who lost his life, of people who were either hospitalized, required stitches or were treated for various problems. These are real cases involving real people.
Getting back to what you said, with all due respect, there may be some confusion here. You're mixing apples and oranges. You're talking about parole officers and corrections officers. Let me just say two things. First, an ex-inmate certainly has no interest in assaulting the person responsible for keeping him out of jail or who has the authority to send him back to jail. Therefore, parole officers face a substantially lower risk at the outset because the ex-inmate wants to be on good terms with his parole officer.
In the case of those officers working in an institutional setting, weapons are close by and there are armed guards on site. If something were to happen, the inmates know full well that armed guards will appear at the scene very quickly.
Such is not the case at the border. There is no police or RCMP presence on site and when they are called in to provide back up, their arrival on the scene is calculated in hours, rather than in minutes.
It's important to understand that border entry posts are often remotely situated. Police officers patrol large areas and often find themselves as far away as they possibly can be from the border post. Occasionally, it may take them hours to arrive at the scene. For example, at the Lacolle border post in Quebec, the RCMP officer called upon to respond will be dispatched from Montreal and it could take quite some time for him to arrive on the scene.
As for senior management's policy of having border officers back off, situations are never black or white. For example, an officer may ask an individual to submit to a secondary inspection of his vehicle and upon inspecting the vehicle, the officer may discover a loaded weapon, drugs or some such thing.
It is a little known fact that last year, if memory serves me well, hundreds of millions of dollars worth of drugs were seized at the border. Recently, a vehicle carrying eight million dollars worth of drugs was intercepted in Canada. Obviously, when a vehicle carrying $8 million worth of cocaine is intercepted, some people may want to take advantage of the fact that border guards are not armed.
