Well, I have a couple things to say on this subject lol I wouldn't punch them if I was her, or do anything drastic like that because it's what they want. That's exactly why they're trying to put these stars in the worst positions possible, so that they react in a negative way because then the paps will get more money. Rather than just "Katy leaving the gym", if they have "Katy punching pap while leaving gym" they'll obviously get more money for the latter.
I consider it all a form of stalking and I don't think it's ethical. They have no respect for the celebrity they're following and could care less about the safety of others in their "hunt." As much as I would LOVE to see stricter laws against this type of disgusting behavior, I don't think we will. The law also gives freedom to the press, and if anyone tries to limit that in any way, then all hell will break loose... there need to be restrictions on their conduct though. These people are ruthless and will stop at nothing to get their money shot, even if it means putting someones life in jeopardy. I think they need to be penalized for their actions, especially if they hurt anyone in the process of pursuing a celebrity. Honestly, if any of us openly acted that way in our jobs I'm sure we'd be fired by now. Unfortunately, those paps who are the most thoughtless often receive the highest reward for their photographs...

If the paparazzi is allowed to over step their boundaries like this, we should express our freedom of speech and say something about it. If you don't like it, take a stand. The more people who oppose their behavior, the more likely it is that someone will hear us and do something about it. If you're ever in an uncomfortable position because of them, make it known. Seriously, if these people ever dare to touch me or even push me at an event, things are getting real.
Also, to anyone that says "it's their job," it's not like they're forced to do this. They have other options. I don't care what anyone says, there are
always other options. The reason they choose this path is because it makes the most money for the least amount of effort.
