I don't think I can make sense of or agree with all the legal intricacies, so I'm going to tackle the logistical ones. From the two bases I've had the time to get to know, at least a litte, (CFB Kingston and Borden), I've noticed that the bases, and more so the PMQ "patches", are someone out of the way from the local town. Now, if I remember correctly, Borden's PMQ's were like a closed in survey, connected internally to the base, so I'm assuming the MPs would have full jurisdiction there, right? Well in Kingston, the PMQs are actually just off base (atleast I think its 'off' base), built right next to a highway and roads that enter and exit off that highway. Even if the land is still actually DND land, the roads definitely seem to be local gov. owned (again, correct me here). Further, CFB Kingston is well segregated from most of the rest of Kingston, with only a single two lane highway connecting CFB Kingston and RMC to Kingston major. If the roads around the PMQs are suppose to be the jurisdiction of the local gov. (and lets assume for the moment they are), then wouldn't it be easier to just hand over jurisdiction to the MPs, who with their closer proximity could more readily provide patrols, security, responses and whatever else it is that police do? Why all the fuss about who's got what jurisdiction. Aren't MPs and local police all just trying to "serve and protect"?
