I would just like to note that the DOJ prosecutors in their press release for the indictment, have indeed touted the maximums, as well as mandatory two-year sentences on each of the aggravated identity theft counts.
"Upon conviction, however, the trafficking count carries a maximum penalty of 15 years in prison and the access device fraud count carries a maximum penalty of 10 years in prison. Each of the aggravated identity theft counts, upon conviction, carries a mandatory two-year sentence in addition to any sentence imposed on the trafficking count."
They don't add up the numbers to get 100 years, some reporter did that. They give the maximum penalties for each count, which gives an ides of the maximum he could get depending on which counts he's convicted of. They don't mean for you to add them all together, but to know that e.g. he could get 2 years if convicted only of the least serious offense, but up to 15 if convicted of the most serious.
