Bongotastic,

I would look at the published principles etc for Military Aid to the Civil Power (MACP) and Military Aid to Civil Community (MACC). Commonwealth terms yes, but in wide use under different names.

Not sure about SOP, but after recent events, i.e. Mumbai and 9/11, 7/7 previously there should be something in the open realm.

Remember the police and fire services work on different principles. After a bomb explosion for example ambulance and fire respond, putting saving life first, making allowance for safety and the police then secure and preserve the scene.

I would suspect in a COIN situation the security forces would dictate such scene access.

Finally I'd leave the thread here.
