When you have to apply real pressure on a pressure point, if the victim is conscious he/she is not going to like it, and will be very vocal abouit it. If the victim has family around and sees you kneeling on ole dad's upper arm and hears him screaming his head off, they might very well try to stop you. Violently. Same if they see you pushing on their teenaged daughters upper inner thigh. Military medicine and the civilian stuff can be very different. I am not saying don't do it, I just want anyone who plans on practicing roadside medicine to be aware...
