Agreed. From the FBI press release on his conviction[1] no mention of the murder-for-hire charge. This conviction and sentencing all stem from the drug-selling business enterprise.
Our war-on-drugs sentencing is quite disproportional, IMHO; imputing societal harms that are unfounded. After all, Mr. Ulbright simply provided a safer way for consenting individuals to enter personal financial transactions.
Silk Road is a drop in the bucket compared to all the transactions arranged over SMS messages and using cash - but we don't hold AT&T and the Federal Reserve responsible for running a criminal enterprise.
