11 POINT SCENE GUARD STORY
I am scene guard. D.I. arrives and wants access but I have SECURED SCENE. I allow him in because he has permission from OC Scene. But I RECORD DETAILS (I PANT because I’m nervous). I direct him towards common approach path because I must CONTROL MOVEMENTS. He leaves and I RECORD MOVEMENTS of his vehicle. I immediately ring the OC Scene because I must BRIEF OTHERS.
I need to piss - AVOID DISTURBANCE!
A cat tries to piss - PROTECT SCENE!

As I’m leaving the media want to talk. I don’t talk because I RESPECT SECURITY but I also DEMONSTRATE COURTESY.
Lastly I ring OC Scene because I must INFORM OTHERS.
