Note, I don't think police should inject anyone with a substance (personally, I'd rather get shot with a bullet than involuntarily shot with an anesthetic), but how is being an anesthesiologist relevant?
The question: "should cops direct paramedic to administer K shots" is an ethics, or a religious, question. Not a medical one. Certainly relevant medical questions can inform the debate; questions such as "how to determine safe and effective dosage of an anesthetic in field situations" "What does the person experience when involuntarily subjected to this drug?".
A very important medical question can be: "How lethal is this technique?" So that the technique's lethality can be properly classified for street use.
Subjecting the person to mortal danger is not anesthesiology. It's ethics, law, and religion.
Uhhhh anesthesiologists are experts in administratering sedatives to humans safely. The connection here seems pretty obvious to me...
This is insane.
