Defendant was not deprived of a fair trial by the introduction of expert testimony regarding typical street drug operations.
Defendant's challenge for cause to a prospective juror was properly disallowed by the trial court, since the totality of the venireperson's responses indicated an ability to decide the case impartially ( People v Middleton, 220 AD2d 202, lv denied 87 NY2d 848).
We find the sentence excessive to the extent indicated.
