As a Red Cross First Response team instructed kinda guy, with experience in all facets of "CALL 911, isolate, protect and make safe and comfortable, while assesing damages, and then sitting there and monitoring until proper medical personel arrive" I will say I still would have buried that pick hammer right between her eyes, rolled her to the median of the road and use her as a traffic cone...
Oh, it was pretty clear the guys leg was broken..lifting him up, and holding him... just made it possible to rip or tear, or further lacerate a blood vessel or vein.. and allow him to go thru further risks..
Plafe the person on their back, immobalize, and restrict movement, insure conciousness, and keep observing, do not administer fluids, or remove restrictive garments or helmet, unless absolutely necessary to stop excessive.bleeders.
You MAY unbuckle or slice the strap on a helmet, depending on the trauma points from impact, but do not rearrange body limbs or neck, or remove helmet..
Insure the person is.safe, and don't sit there rhbbing his shoulder over your lamenting...
Id stick a knife in her throat...
