in danger? >> you don't know. look, in 2002 tom gamboa got a permanent hearing loss in his right ear because two fans attacked him. do we know what they were going to do before-hand? no. until a knife came out of their pocket. >> i see your point, richard. >> you don't know what people are going to do until they do it. a police officer does not read minds. >> you're right. >> we have to deal with what we know at the time. >> petra, to that point in 1993 we saw what happened to monica seles when attacked by a fan with a knife. but the last question i have for you, are we tase crazy? >> right. i mean, i think it has the real potential for abuse because police, there is policing to do and if you can see the person doesn't have a weapon, it's an unarmed person, for a very minor, relatively minor offense, they shouldn't be tased given the dangers that tasers pose. you need to do policing. you can't escape that. if you need to use some type of force and muscles to remove that person that's what you need do
