What is the basis for a defense counsel's failure to object to inadmissible evidence?

Assuming the questioning exceeded the scope of the trial court's ruling, the record is silent as to the basis for defense counsel's failure to object. "We have long recognized that counsel's decision whether or not to object to inadmissible evidence is a matter of trial tactics. [Citation.] Because we accord great deference to trial counsel's tactical decisions, counsel's failure to object rarely provides a basis for finding incompetence of counsel." (People v. Lewis (2001) 25 Cal.4th 610, 661.)
