Her husband should suggest they go on a vacation to a beach in Yemen or a lakeside resort in Afghanistan and then explain to the local men what she is famous for, let them handle her sharia style. Then he can move on in life.
Some guys will tolerate anything. It is bad enough she cheated on him... It is bad enough she cheated on him with 6 other guys. It is bad enough she did this in a way it became international news and a trending meme... He stuck by her and said he won't leave her. That is not love, that is simply his being a simp and a beta cuck.
The entire world knows what she did and knows that he won't ever enforce any boundaries or standards.
Any one of us could walk up to that guy and rob him blind, ordering him, "strip down, wallet, phone, shoes, shocks, pants, give it all up" and we could violate his back door if we were into that. He has already signaled to the world that he will tolerate anything and he won't ever draw or enforce any line.
The guy is still a cop.
I couldn't ever accept a ticket from him. If he said, "do you know why I pulled you over?" I would probably respond with, "because your wife is off letting a squad run a train on her and you weren't invited?"
