Sentencing.

Existing law provides that most felonies are punishable by a triad of terms of incarceration in the state prison, comprised of low, middle, and upper terms. Previous law that required the court to impose the middle term, unless there were circumstances in aggravation or mitigation of the crime, was amended to provide that the choice of the appropriate term rests within the sound discretion of the court. Existing provisions related to sentence enhancements involving criminal street gang activity, firearms, and sentencing generally specify that the court shall impose the middle term of a triad of sentence enhancements unless there are circumstances in aggravation or mitigation of the crime.
