I hate it when people claim it's all in line with Obi-Wan's cover-up to Luke. Yeah, right. As if there's any real threat to national security to admit, "Yeah, I know that little domed guy and that gold guy." I mean, that would be like listening to Leia's message and have Obi-Wan say to Luke, "I-I-I didn't know her father. I don't know what she's talking about. Clone Wars? What are those?" And then to himself, "Phew, glad I covered that up. Now Luke will never find out about his father."

The simple solution: not have the droids in the PT. They don't belong. Nothing feels more forced in all the prequels than the inclusion of R2 and 3PO. And I love how Lucas claims all the time that characters don't just wander into a story. Well, they certainly wandered into the prequels and never left!
