The speculation about the time this guy will get is quite amusing. I also find the comments like where people claim someone who wasn't a LEO officer, in the same stituation "most certainly would do hard time," amusing too. The speculation and comments about non-LEOs doing more time show extreme ignornance of how sentencing in the federal courts works.
1st, federal judges are no longer required to sentence according to the federal sentencing guidelines, BUT the vast majority of the time they do follow the guidelines.
2nd, the sentencing guidelines are the same regardless of whether someone is a cop or not.
3rd, the 10 years/$250K is the max, not what everyone gets for violating the law. Several factors go into determining how the guidelines are used to calculate the sentence, including prior criminal history and whether the defendant accepts responsibility.
4th, this guy is unlikely to have any prior criminal convictions, which puts him at the very bottom of the sentencing guidelines. Further his guilty plea and acceptance of responsibility will likely get him a downward departure from the guidelines.
Therefore unless the judge decides to depart from the sentencing guidelines, it is unlikely this person will do much, if any, jail time. However, he will most likely have a couple years of supervised release, aka probation.
The things I just explained would happen to anyone, regardless of whether they were an LEO or not.
