How has section 654 of the California Criminal Code been interpreted in the context of street terrorism?

A little over 10 years ago a different panel of this court first addressed application of section 654 in the context of a street terrorism charge in People v. Herrera (1999) 70 Cal.App.4th 1456, 83 Cal.Rptr.2d 307 ( Herrera ). In Herrera, defendant, a gang member, fired three shots at a rival gang member's house from the front passenger seat of a vehicle. One bullet struck an 11-year-old boy and another bullet struck a man in the left shoulder, breaking a bone. The vehicle then made a U-turn and returned for a second pass, and approximately 10 additional shots were fired but no further injuries were inflicted. A jury convicted defendant of a variety of offenses including one count of street terrorism and two counts of attempted murder. ( Id. at p. 1462, 83 Cal.Rptr.2d 307.) In pertinent part, the trial court imposed a separate term for the street terrorism conviction. On appeal, defendant argued section 654 prohibited the imposition of a separate term on the street terrorism conviction.
