There is a core of the opposition in the population that will not be satisfied regardless of how much proof is shown, but the rest will accept, and move on. We're not that far apart as Americans yet, we still have more shared characteristics than differences. Doesn't mean I won't be expecting some action soon though.
Bottom up to get the public used to the idea that this is happening with lower level prosecutions so when it's time for the big names it will be more understandable.
I figure a lot of the opposition is either from foreigners or foreign-controlled actors. A lot of them look and talk like Americans now, they are hard to pick out. Drain the foreigners, drain the opposition.
