I agree with harsher penalties for those that attack ambos @greenpea but it still needs to be done on a case by case basis. For example those that have had a big night out and are drunk and attack someone is very different from someone who is having a psychotic episode. It is a really hard one to deal with though as both alcohol/drugs can cause an individusl to act in a way that they would not normally act when sober.

I don't think goal is the answer then - rehab may be better for those people - don't know - I am putting this one in the too hard basket for my brain today
