Well, if Anakin were to start fighting against Fett & the Destroyer Droids, what about Padmé? She doesn't have a weapon to defend herself, and Anakin just saved her from imminent doom. Does he put her back into imminent danger by attacking instead of surrendering? He's not going to do that because they're likely to just kill her (which is what the Geonosians end up wanting, anyway). Their mission here is to rescue Obi-Wan, and prevent an all-out interstellar war. Continuing to fight through every obstacle in their way isn't what Padmé wanted.

And dark_jedi, I use Final Cut Pro 5.1 on a Mac G4 running OS 10.4.11.
