I truly don't see the problem if it's being taken against their will. That in and of itself provides the opportunity for people to go sideways, nevermind the fact that alcohol is involved, which makes almost anyone unpredictable. If I had to make an educated guess, it's probably because they have a civilian nurse doing the blood draw. That person is at great risk when dealing with a needle and someone who is under the influence of alcohol having a procedure done to them against their will. What the general public doesn't hear about is the large number of cases in HOSPITALS, not jails where these same types of draws were being done without people in restraints. ER staff have been injured, stuck by needles and even held hostage by people with the very needle being used to do the draw.

I can tell you much of that has stopped because hospitals have put policies in place to restrain any of these people during blood draws. I mean how horrible is it really when someone is strapped down for all of the 30 seconds or less it takes to do the draw and then the restraints are taken right back off. It helps keep civilian medical personnel safe. Almost every non-compliant person starts out as compliant at some point. Humans are always unpredictable even without the addition of alcohol into the scenario.
