In the first scenario where Sam Smith committed a robbery in possession of a firearm, the type of sentencing model I would use is a determinate sentence. I think determinate sentencing would be ideal because Sam did accept his responsibility, had no previous criminal record, and no one was injured. He would receive a fixed sentence term for his actions and if he were to have good conduct in jail then he would qualify for an early release based on conduct.
The actual sentence I would impose would abide by the Florida minimum mandatory law because of the firearm he was in possession of. To which would sentence Sam to be incarcerate for 10 years in prison for possession of a firearm even though he did not fire his weapon or threaten anyone with
