Even in a perfect world, where cops actually protect and serve the people, if you're going to send cops to a medical emergency they should only be there as a helping hand to paramedics. If the paramedic tells the cops to fuck off, they should comply. Cops aren't medics, they're not trained to properly handle really any medical emergency any more than the average person who's watched greys anatomy. They have no business being there and if they are they should be the bitch boy to the actual trained professional.
