Most of the responses are correct unfortunately there are only a few things you can do to try and preserve the patient's privacy. You can do your best but the best you can do is quickly package up the patient and get them into your ambulance where you can control the environment. The other thing is try to get the police involved as needed by keeping the crowds back and allowing you to do your job. I have found most cops prefer not to do your job and faced with the possibility of holding back drunks or getting there hands dirty with patient care most cops prefer to hold back the drunks
