The vics exited the vee-hicle under their own power.
Someone else wants to be in charge - good leave.
They can't sue me. They have no ideal who the hell I am.
The only exception to this is when the other "folks" on the scene are obviously not up to it.
My training level (now quite out of date) dosen't really have a suitable civilian equivilent. I was a 8404 Corpsman,(HM2) and had done a big hunk of my time doing medevacs in the field, boats/ships and water. I also did a lot of ER time, along with ortho, lab, x-ray, etc.
While a civilian photojournalist, I responded to numerous scanner calls - I've pulled line on brush trucks at fires while the full time firefighters were waiting for all the volunteers to catch up. I also responded to one that was a fall from the roof of a three story apt. building under construction.. Sadly, even with rescue one and the ambulance there, I was still the most experienced, so I put down my camera bag...
The arguement I have most often - REFUSING to let ANYONE move a vic until EMS takes over...
I (another corpsman and myself) did pull 2 cute early 20's girles outta a flipped pickup truck.
As soon as I saw the fuel spreading, I sent bystanders back over a 100 meters to block the road and he and I cut 'em outta their belts...
This is the ONE time (out of literally dozens) I moved a vic when I wasn't the EMS on the scene...
