The story of the two “wronged” border patrol agents is still circulating in conservative circles. Read the statement from the US Attorney who prosecuted them (warning: PDF). It deals with a lot of shibboleths being spread by the Right.
One thing I will comment on: reading between the lines, I think Johnny Sutton thinks the 10+ year sentences were excessive as well. But a Clinton-era law puts in a mandatory 10-year sentence for using a firearm to commit a felony. So he had no choice.
I hate mandatory sentences in general and this business of tacking on extra years because a gun was used violates the right of due process. These men were given an extra ten years for a crime the jury never convicted of. And we have seen this guideline abused over and over again — in Texas, against the Branch Davidians, for example.
Perhaps if conservatives focused their energy away from the prosecutor and onto the unconstitutional insanity of 10-year sentence mandates, we’d make more progress.
