I have to say that this looks very odd to me. I'm in Rota's riding, and he hardly ever takes any action visible enough to make the news here. And now he takes a highly visible action that's going to trash his political career (regardless of whether he resigns or not, I doubt he's going to get reelected after this—rumour has it he won't run). He's been in politics for quite a while, and he should have known better. It's possible that he simply got complacent and careless, but I do wonder how he knew that this guy existed in the first place.
