Decades ago, we had a DOJ that filed criminal charges against corporate executives that did crimes.
Today, our cowed, stuck-on-bad-process DOJ merely negotiates ineffective fines with their companies (through deferred prosecution agreements.)
We need to reform DOJ so that we prosecute white collar crime again.
As has been said many times, the two books by Jesse Eisinger and @jentaub are guides to what has gone wrong and how to fix it.
