What is the current state of the law with respect to counsel's tactical decisions?

"`"Reviewing courts defer to counsel's reasonable tactical decisions in examining a claim of ineffective assistance of counsel [citation], and there is a `strong presumption that counsel's conduct falls within the wide range of professional assistance.'" [Citation.] "[W]e accord great deference to counsel's tactical decisions" [citation], and ..."courts should not second-guess reasonable ... tactical decisions in the harsh light of hindsight" [citation]. "Tactical errors are generally not deemed reversible, and counsel's decisionmaking must be evaluated in the context of the available facts." [Citation.]'" (People v. Stanley (2006) 39 Cal.4th 913, 954.)
