Consensual Sex Doesn't Mean It's Okay

I'm not about to convict City Councilman Dennis Gallagher who has been charged here with raping a woman in his district office. But I will say that he did do something wrong - he had sex with someone that wasn't his wife. Stating that the sex was consensual shouldn't get him off the hook. It would seem to me that men like Councilman Gallagher think that its ok for them to say "the sex was consensual" and that relieves them of all responsibility. What was he doing picking up this woman in a bar when he should have been home with his wife and kids?
