In Oz there is no reluctance at all on charging almost anyone who assaults an ambo. The ambulance service and police are very proactive on this front. An assault on one type of uniform.... The one area where they are reluctant is where there is a question of a psych hx. The police are under impression that charges wont hold up in court. Have explained many times that just because there is some psych element involved does not mean that insight was absent nor absolve personal responsibilty for actions
