I love how he calls everyone arm-chair lawyers and con-law professors mockingly then goes on to state a legal opinion, he just squarely put himself into the above category. Good job, Dave! Also, good job on paraphrasing with a picture. You missed the part where the Judge also said "It doesn't seem fair, and I know my criminal law professor would yell at me for saying that..." But let's see what a tribunal of Judges said...
Given the seriousness of arson, a five-year sentence is not grossly disproportionate to the offense. The Supreme Court has upheld far tougher sentences for less serious or, at the very least, comparable offenses. See Lockyer v. Andrade, 538 U.S. 63 (2003) (upholding a sentence of fifty years to life under California’s three-strikes law for stealing nine videotapes); Ewing v. California, 538 U.S. 11 (2003) (upholding a sentence of twenty-five years to life under California’s three-strikes law for the theft of three golf clubs); Hutto v. Davis, 454 U.S. 370 (1982) (per curiam) (upholding a forty-year sentence for possession of nine ounces of marijuana with the intent to distribute); Rummel v. Estelle, 445 U.S. 263 (1980) (upholding a life sentence under Texas’s recidivist statute for obtaining $120.75 by false pretenses). And we and other courts have done the same. See, e.g., United States v. Tolliver, 730 F.3d 1216, 1230–32 (10th Cir. 2013) (upholding a 430-month sentence for using arson in the commission of a felony); United States v. Major, 676 F.3d 803, 812 (9th Cir. 2012) (upholding a 750-year sentence for offenses under 18 U.S.C. § 924(c)), cert. denied, 133 S. Ct. 280; United States v. Meiners, 485 F.3d 1211, 1212–13 (9th Cir. 2007) (per curiam) (upholding a fifteen-year sentence for advertising child pornography); United States v. Uphoff, 232 F.3d 624, 625–26 (8th Cir. 2000) (upholding a five-year sentence for arson of a building).
Ouch. That's what three judges from the Ninth Circuit Court of Appeals ruled. There goes your argument.
The prosecution could have done two counts of Section 844 to form a ten year sentence, but decided to be lenient and recommended concurrent sentences instead. Huge, huge, huge, overreach.
