Cap could have gone on national TV like Hawkeye did- Clint said that Osborn's Dark Avengers were crimminals and that his team would keep fighting for the people, no matter what.

He got national attention- and if Cap had done it, he'd have had a platform to repeal the law...or at lest get the database part modified.
Or you know, trust in the people he's supposed to represent to do the right thing.

If nothing else, all those old WWII vets would have called their congressmen- geezers always vote!
