I have several friends who have worked as strippers; one has a PhD and another works as a children's therapist, and I can imagine either -- alongside other women who work as strippers -- being offended by an offensive man uttering offensive remarks, if Britt did indeed say them. Working as a stripper, even in rural TN, does not imply bad character, and it's notable that although we have heard things attributed to her, we have heard nothing directly from her, yet. Maybe she's a bad apple, maybe not. I don't think her (former?) occupation is proof of anything, except that it may have put her in closer ontact with ZA and his crew.
I agree with others that ZA's attorney is laying the ground for an "It was someone else wot done it" defense.
