Song did not object in the trial court to the use of the prior conviction to enhance his sentence under a statute permitting enhancement for dangerous felonies committed while on release. Id.

The court of appeals reached Song's arguments on the merits and concluded that the Arizona statute required a person to knowingly possess a firearm while the foreign statute only required reckless possession. Id. at 215-16, 860 P.2d at 482-83.
