Good and Bad behaviour
When you eliminate the risk from bad behaviour people tend to behave badly!
The teenage keyboard warrior springs to mind, he sits on his laptop that mummy and daddy bought him and responds to anyone that dares to question him with a barrage of abuse and harsh language (this is not just limited to teenagers, adults do it too).
The risk is removed because the people he is abusing don't know who or where he is. Put that same person in a bar or public setting where he can be physically held accountable for his abuse and you get a different person!
