What crime has been committed?

That's the wrong question. The right question is, "What crimes can be construed to have been committed, in order to put enough people in jail for long enough sentences such that the chain of malicious and destructive financial misconduct which lead to the crisis can be severed?".

We put Capone away on tax evasion. Get creative.

Maybe I’m the only person who thinks this, but I think your line of thinking is very dangerous and way more dangerous than ANT or SPCX.
