I don't mean to sound like a cynic, but: I don't think much will happen unless the number of protesters is in the many millions. Here's why: think back to Occupy. What did that movement want? A simple prosecution of the criminals who precipitated the 2008 crisis. But till date nothing has happened. Here we're talking about the government itself committing violations; what are the chances they'll do anything, when they did nothing to the bankers?

TL;DR: the only way we have a chance in hell is to have a HUGE turnout.
