Soldiers are usually ill-equipped to do police work. Soldiers are trained to kill people and blow up things, while police are, for the most part, trained to subdue and enforce with a minimum use of force, only escalating to a drawn weapon as a last resort.
Some soldier groups, noticeably Canadian forces, are trained from the beginning to be cops, or peacekeepers who can resort to calling in airstrikes and artillery as need be. If you remember the Oka occupation by a group of very angry native Canadians, you remember the photo of a young Canadian Soldier going face to face and toe to toe with a masked Oka warrior. The soldier never looked away and never blinked. That was training as a peacekeeper and as a security force that helped that soldier keep his cool.
The US forces are trained as war fighters, which they do very, very well. Peacekeeping is not their forte, but it is the Canadian skill. Perhaps it is time for Jean Chretien to pull his head out of his ass and offer up our folks, renown as the best, most effective, fairest peacekeeping forces, to do our thing.
As a side note to all American Forces. It is pronounced “Cash” and is spelled ‘cache’ It is not pronounced ‘cash-eh’. The word is French and means box or container. A Brazilian thong bathing suit is a ‘cache-sexe’ or literally translated, sex parts covering or box. Remember it is pronounced: “cash”. Thank You.

That’s the problem with you bloody Canucks. You’re all too bloody worried about damaging something. Think of it this way – if you’re a cop, you have to police (the verb), which requires long hours and a great deal of effort on your behalf. It takes 3 minutes to call in an airstrike, and about as much effort as chewing a piece of gum. So just blow the crap away, and get over yourselves, eh? Then you can get back to your moose and your beer and your bloody curling, you great bunch of syrup-sucking wankers! :p
(There, if that doesn’t get you some responses, Dave, nothing will! :D)
