Bascically it comes down to accepting responsibility and don't piss off investigators/prosecutors or you'll get the book thrown at you. This is from another site, posted by a guy who was actually caught with a FEW unregistere machineguns and suppressors. The guy was not a violent criminal or dealer. He was just a collector of certain restricted items. Guy got pulled-over by a cop on the way home from the shooting range they found illegal machineguns (an AK and MP5 and silencer, I think). He cooperated, was honest and did his time. Another guy in the car had some other unregistered NFA items as well as drug possesion (the other guy was basically a shithead). He was not so cooperative and ends up facing 2X-4X more time despite having fewer illegal NFA guns.
...The feds use the Sentencing Guideline Chart to produce sentencing ranges based on a point system. The chart takes several factors into account including base offense level (most serious charge / 26 USC 5862(d)), number of offenses (number of guns / two), prior criminal history (first time offender) and acceptance of responsibility (two point reduction). There's also a victim impact / violence assessment but that wasn't a factor in my case. I was initially charged with possession of two machine guns, had a criminal history of zero and accepted responsibility. Had I plead out under my original indictment, I would have had a point score of 15 and been looking at 18-24 months.
******* really fucked me over by having his lawyer float that ridiculous incomplete ATF registry database defense. The prosecutor superceded the indictment with a drug user in possion charge. What that did in my case was cause the Glock 17C to count against me under 18 USC 922(g)(3). That moved me from 1-2 guns to 3-7 guns. That increase in firearms moved me from a score of 15 to a score of 18. That meant I was looking at 27-33 months instead of 18-24 months. The prosecutor made a point of saying that this wasn't happening because of *******, not me. Yeah, that's nice, but I'm still getting fucked over.
The sentencing board recommended 18-24 months, 27-33 months. FYI, they agreed with the prosecution's range of 37-46 months in *******'s case. The prosecutor objected to their recommendation in my case during my sentencing hearing. It was the first time in my attorney's 14 year career that he'd seen the sentencing board recommend a lower sentence that the prosecution's calculation. The judge ruled that the facts of the case did not support the prosecution's 27-33 month calculation.
The 18-24 month vs 27-33 month difference essentially depended on whether I had two prohibited items (two MGs) or three prohibited items (the two MGs plus a Glock 17C) under the law. The irony was that I had at least three prohibited items (two MGs and one suppressor), but neither the original indictment or superceding indictment listed the suppressor. I have no idea why. It may have simply been a mistake. But that omission is what allowed the sentencing board to recommend 18-24 months instead of 27-33 months.
The prosecutor and judge then debated the relevant sentencing issues. There are four criteria: risk to the community, risk of reoffense, deterance to crime and uniformity in sentencing. Both agreed that I was not a risk to the community or risk of reoffense (I appreciated that being stated for the record). Deterance was a minor issue. Uniformity in sentencing was the primary concern. There are a lot of special interest groups that monitor disparities in sentencing for "similar" defendants. Education, employment and likeability aren't factors in sentencing guidelines. Neither is race, but race is often viewed as the deciding factor by special interest groups when they see very low sentences for people like me.
Federal Sentencing Guidelines were mandatory up until 2004. If your recommended range was 18-24 months, you received a sentence between 18 and 24 months. No exceptions. The Feds have a strong bias towards adhering to sentencing guideline ranges. The judge gave me a year and day. That was a very low sentence which corresponded to a score of 13 or lower. It's not mathematically possible to get to 13 with a base level offense of Possession of Unregistered Machine Guns. The judge had given me a huge break.
The prosecutor was clearly angered by the judge's decision. It had nothing to do with me. It had everything to do with guidelines dictating 27-33 months or 18-24 months depending on whose calculations you used. A year and a day was substantially below either guideline range.
Also, the fact that I was sentenced to a "a year and a day" instead of "12 months" was significant. Sentences under one year are not eligible for Good Time Credit or halfway house. Receiving "a year and a day" meant I would be eligble for Good Time Credit (47 days) and halfway house (up to 6 months). So I would be serving 4 1/2 - 10 1/2 months in prison instead of 12 months. I ended up serving less than 8 months in prison and 2 1/2 months in halfway house.
I wasn't fined, but there was a mandatory special assessment of $100. So my full sentence was "a year and a day" with a $100 special assessment.
******* spent 8 1/2 months in federal detention (not prison) prior to being sentenced because he violated pre-trial release conditions (3 failed drug tests, threats against law enforcement). His attorney presented a diminished capacity defense at his sentencing hearing, but the judge struck it down. In the end the judge cited his real military service (3 1/2 years army) as a mitigating factor and gave him time served. The prosecutor was pissed. I can't prove it but I think that's the day *******' stolen valor investigation really began. (Background Info: Shithead has a long history of severely impersonating/lying about military service/awards for significant personal gain. He's currently being wrung through the system on stolen valor charges.)
