The sentences reported in press releases when someone is indicted are derived by adding up for each charge the maximum sentence that it is possible for anyone to get for that charge, and then that total is reported. That is nowhere near what the person actually faces in almost every case. There are three things under the Federal Sentencing Guidelines that greatly reduce the sentence they actually face.
First, the maximum sentence for a given count is only possible for the most severe instances of that kind of violation.
Second, priory convictions are taken into account. To get the maximum sentence, you have to pretty much be a career criminal.
Finally, felonies are divided into groups. If you are charged with multiple felonies from the same group for the same underlying acts, you will only be sentenced for one of the felonies in the group.
The Federal Sentencing Guidelines are non-binding, so it is possible for a judge to sentence someone to more than the guidelines call for, but such sentences are almost always reduced on appeal to something in accord with the Guidelines. I've not seen anything in the Sabu case that would make it an exception to this.
