First, I don't think he deserves a lower sentence because of his military career. Why should he get less time than anyone else who breaks the law? Second, this article isn't telling everything. He wasn't just charged with possessing an unregistered M14. He was also charged with possessing 14 other firearms and he was a prohibited person under federal law. (unlawful user of controlled substances.) He was also charged with the removed serial number which is also a crime.

Here is the kicker for all you guys, he didn't even plead guilty to the charges associated with the M14. They were dismissed. He plead guilty and was sentenced for being a unlawful user of controlled substances in possession of a firearm. When they searched his house, they found a good amount of marijuana and cocaine. He admitted to being a drug addict. Therefore, under current federal law, he isn't allowed to possess a firearm.

Lastly, he was mentally evaluated and determined to suffer from schizophrenia and bi-polar disorder.
