Is defendant represented by a single attorney during the course of his prosecution?

^4. The record shows defendant was actually represented by multiple attorneys over the course of his prosecution. In the conclusion section of his opening brief, he alleges he was "haphazardly '[k]icked around'" by his attorneys. However, other than faulting them for not contesting the charges under subdivision (d), defendant does not explain how his various attorneys failed to provide him with effective assistance or otherwise mistreated him. Therefore, we need not delve into his Sixth Amendment claim any further. (See Paterno v. State of California (1999) 74 Cal.App.4th 68, 106 [appellant has the duty to explain the basis for the claims he raises on appeal].)
