I came across your thread/post during a google web research project tonight, I know it's old but thought you might be interested in my personal feelings regarding this topic since I have been a fairly active street medic for a little bit now. This is purely my personal opinion.
Let's start with... I've had brief interactions with Kristen and I feel she is a nut. Actually, all you have to do is look at her web site and read most of her articles and anyone would be able to see that. When I asked my friend about her who has been an activist/medic since the 80's, she even went as far as calling into question whether Kristen is a medic or not since she does not run with the majority and is rarely active. Primarily, Kristen is a writer.
Next... Her article, The reason this article was written was as a result/reaction/defense of her making this statement on the action-medical listserv which basically got her flamed off the list and branded as a nut.
Lastly, My background and personal feelings on this topic. I have been a nationally registered EMT-B for about three years and have been running on the streets as a medic for a little longer. I am highly active in BARHC (Bay Area Radical Health Collective) as their web master and help with overall organizing. I mostly have mediced at bay area demos but was also in NY for the RNC (web mastered the NoRNCMed site and ran the entire week as a medic).
Just a note, I would not treat a cop for blisters or slight dehydration, that is what their line sergeant is there for... but, I personally feel medics should treat police and counter demonstrators if life or limb are in parrel though, but you have to weigh scene safety first (is it safe to approach?).
There would be no need for us to approach that officer if he was not alone, he would have been already evaced long before we had a chance to treat them and/or it would be IMPOSSIBLE for us to get access. So, since the officer is alone, that leaves us with a injured, scared, compromised, alone officer with a high probability that he would shoot first ask questions later. Each situation would need to be weighed heavily, a dead hero is a
dead hero.
Although, I did hear a heart warming story as a response to this topic being brought up on the action-medical list as follows. This would be the type of situation that a medic would be treating a wounded officer under...
There was an officer that got split off from his line in the mid-west, all of the sudden he got swarmed then got hit in the face with a stick or something. There was blood coming down his face and he couldn't see anything. He drew his gun and started pointing it around and screaming, people started panicking and freaking out... then some medics came on scene. They shouted thathe was safe and they were there to help him if he calmed down and put his gun down. They kept talking to him as they slowly approached him telling him their every step. They cleaned off his forehead and eyes and got him an ambulance then went on their way anonomously.Another story, from while I was in New York, it was the Sunday big UFPJ march there was this officer tracking me and following me around trying to intimidate me, I wandered off and he lost track of me. about a half hour later I came up to a scene where someone screamed for a medic, there was a 14y/o Jersey girl coming in and out of consciousness from heat syncope, she then stopped breathing. Once she started breathing again we evaced her into an apartment building, the officer saw this and almost immediately after we transfered her to EMS that officer came running in saying a guy was having a heart attack a block away. Him and 4 other officers escorted us to the diabetic guy who collapsed (easy mistake

).
Honestly I do not like cops, I've had to treat too many people who were victims of their usually unprovoked attacks. But I do not see them as the enemy and any way of opening doors is a good thing, we are there for the groups overall safety just as they are supposed to be there for. Treating a cop would lead to one more open door and one more cop that might let us though a line to treat an injured person.
Another note, remember, ambulances will not approach an unsecured protest zone so that is why we put our ***es on the line to sometime care for critical injuries and get those people to a place where the ambulances will come.
Hoped this helped.
