I think you could make an argument either way and have an equal chance of being right. Either Trump et al get bribed/flattered/are personally exposed to the fallout and bail out their fellow class members or he gets angry about it and decides to make heads roll via his increasingly captured and controlled DOJ. I still agree it's more likely the former than the latter but I can see the path that leads to the latter.

I'm shocked, shocked to find that gambling was going on there.

Maybe I'm reading too far but "heads will roll" has connotations outside the strictly legal sense
