Interesting discussion of the pattern of criminality and RICO prosecution, with regards to Trump: Ruminations on RICO and Asset Forfeiture
Most interesting is that elements in the pattern can include settled civil cases and No Contest pleas that resulted in fines for the last 10 years! So many Trump Organization acts qualify it for RICO prosecution. Such prosecution only requires two such acts, but the Trump organization has committed thousands of frauds in the last 10 years. The Trump University findings alone contain over 5000 acts of fraud. Trump's phony charitable Foundation is a whole additional element: Every single solicited donation that was misused is another fraud.
So when a Democratic President has a real unfettered Justice Department, Trump is toast. And probably penniless.
