I actually don't blame Baldwin here.....paparazzi are a pain-in-the-ass.
The paparazzi are part of the deal. You get fame, fortune, and incredible privilege. On the down side, you lose the ability to be anonymous, and get the paparazzi hounding you. Don't like it? Don't accept the former, you won't get the latter.
Somehow, other stars manage to accept the deal without trying to accost a member of the paparazzi.
I do blame Baldwin, and I'm disappointed that he didn't get charged.
