We will sincerely try to make this the last time we talk about this guy till sentencing. Subway stroker suspect Kevin Bishop, who was observed and photographed self-straphanging on the 3 train and arrested yesterday, turns out to have 64 priors, a “history of failing to appear in court” (per the Post), and a very poor excuse — he says he just looked down and there it was, his tackle out of the box. “It just popped out. I was trying to put it back,” he tells an overwhelmingly skeptical public. Bishop goes back to court Tuesday.
