I suppose I should know better than to post after a long irritating day, or at least to provide some context if I'm going to be particularly contrary...
My comments, rounded out, in reverse order...
Oh, and lose the black "wanna be OPP" uniform, while we're at it...
"Uniform" means just that - everyone the same. Different dress does breed divisions; if there is a desperate need for a garrison dress for MPs make it similar to extant CF uniforms - to remind both the CF population at large and the MPs that they are all part of the same team.
And replace the NIS with an RCMP det that's fully outside the CF chain of command.
As long as there is potential chain of command involvement in investigations there is potential chain of command interference. Not a good thing. In addition, the MP population is small enough ,with significant churn in the lower ranks, that building the requisite depth of competence for the requisite investigative skills is a problem, particularly since the military posts on a regular cycle - most civilian LEAs have long-serving officers engaged in sensitive and complex investigations, not the steady churn the military provides.
Some would argue that this could be avoided by extending tours at the NIS; I'd oppose that (and initiatives to extend tours in other occupations as well) as eroding the experiential pillar needed for professional development - a good military has a small nucleus of specialists, but most should be generalists within their trade.
Strip them MPs of their credentials. Hire the RCMP to police the PMQ patch. Restore the M in the MP to its proper prominence.
I have never seen any adequate justification for all MPs to be credentialed peace officers. Domestic policing is not a military function, and it can be readily contracted out, freeing up some of the limited military PYs we have available to meet other military requirements. Vital point security? Yes, a valid role for the MP. Route marking? Another valid role (that modern MPs don't care to do). Care of PWs? Yet another fine task for MPs.
We have now an MP branch whose focus is almost exclusively on the policing aspect of their job. What's needed is a renewed emphasis on the combat service support aspect of their job.
Or, to put it in its most basic form:
Are they cops, or are they soldiers? They can't be both.
