I do not recall any instances of that happening.
I read back through quite a few of your previous posts both to see if you had ever clearly stated or indicated that you were an MP and to get a better general impression of you.
We tend to agree on the same things, actually, and I am not surprised.
But commissions and ranks and appointments DO mean something in a military organization, and much more so than positions in any civilian company. I have been on a base where MPs did not feel that they had to salute an Officer at any time. There is nowhere in the NDA, or anywhere else that I know, that gives them any such exemption. I am rather easygoing in general, and do not take offence if somebody misses a salute as rank is not always blatantly obvious on some uniforms, however consistent misses by members of a certain community is rather irksome. I greet all those whom I pass in the opposite direction with a polite "good morning/afternoon/evening" etcetera, MPs included, and a salute where warranted. Why can't they offer the same courtesy?
As for the then-Major Wellwood case, would an MP have considered it acceptable to brush off and physically push the CDS in his HQ? The VCDS? Commander Canadian Army? A Brigade Commander? How about a Battalion Commanding Officer? Where is the line drawn? Between Battalion Commanding Officer and Company Commander? These people have been granted the power of Command, and very significant responsibility. Claiming that they have no more status than that of a homeless person (who still has the right to be treated decently and not wantonly shoved around) while they are conducting their duty and exercising their authority is ludicrous.
And no, ExRCDcpl, nobody is trying to "discredit" you for being, either in the past or in the present, an MP. There was sufficient implication via your posts, intentional or otherwise, that I decided to have a closer look. People are naturally curious. I do not hold MPness against you or any other MP, and I have a reasonable appreciation for the difficulties of your job as either military or civilian police. I have had many friends over many decades who are or were police, and I have been a Pilot on two police helicopter trials.
I will not slag anybody because of their occupation, nor would I attempt to defend a fellow Pilot who was a knob or did wrong - or myself, for that matter, as we can be very self-critical.
