Excellent point!
That raises another problem for Ford: If he is indeed reliant on crack cocaine to control his stress or whatever, with all the pressure he's under right now if there were any time that he's needed it the most, this is it. But he's being monitored everywhere he goes and with a price now on his head, this is easy money. Private detectives, other members of the drug trade and any opportunist could be waiting for Ford to make his next mistake. Either way, he's screwed.
That's why resigning would be his best strategy. He admits the video is real and suddenly the video is not so important because he's just confirmed its authenticity. He gets the press off his back and takes a nice extended vacation out in Florida with his family then comes back with another chance. Will Toronto forgive him? I think many of his strongest supporters would, while many would not want a repeat of the last 3 years. But it's the only shot he's got.
