What is the current state of the law on aggravating and mitigating factors?

"The particular weight to be afforded aggravating and mitigating factors 'is a matter firmly committed to the discretion of the sentencing judge,' with appellate courts seeking to ensure only that a factor 'can bear the weight assigned it under the totality of circumstances in the case.'" United States v. Broxmeyer, 699 F.3d 265, 289 (2d Cir. 2012) (internal citations omitted). "In making that determination, we are mindful that 'facts may frequently point in different directions so that even experienced district judges may reasonably differ, not only in their findings of fact, but in the relative weight they accord competing circumstances.'" Id. (quoting United States v. Jones, 531 F.3d 163, 174 (2d Cir. 2008)).
