Rolling into the game late after being too busy and distracted to post anything for ages... I'm sure most know the following but maybe not, so:
There already is a forum for MPs to have private discussions, check out the
Association website for how to register and gain access or speak with your Regional Rep.
Should you desire just to shoot the breeze with MPs and retired MP/Provost/RCAF Police on a non-pay site, check out Myke Hamm's site,
CAMPVETS. For some strange reason, this one is much more active than the CMPA one. I guess MPs are a tight fisted bunch who can't bring themselves to pry their wallets open to part with the pittance charged for membership.
If you want to correspond with a cross-section of the Cdn LE community in a closed forum, go to
The Blue Line Forum. There are MPs who are active and <gasp> respected contributors there.
So, in addition to the administrative/security difficulties presented by Mr Bobbit and others, there's no reason to re-invent the wheel here.
Finally, regarding the suggestion to turn to your MDT for getting in contact with MPs, that works fine for those in a patrol car. Not all MPs work with SAMPIS and are SOL on that front. I'd also humbly suggest that your Pol Ops would much rather you be working vice hiding out behind the rink PMing Bloggins in Comox about what happened on the last episode of 24...
