This brings up another point that struck me about the situation as described in the article. The author's friend was "supporting the back" of the injured woman: why? Why not just let her lie still, with something soft under her head, and something else under her feet to keep them elevated, until the EMTs got there? The fact that one bystander was holding the woman up might in itself have struck the cops (and the firemen) as unusual, not to mention a possible cause of damage to the patient.
