In what world do you live where you underestimate the tenacity of New York City cops? Whether by news or fictional portrayals, you’ve had to learn, at some point, that they’re ready to do anything and not exactly soft in their tactics. So, for some crazy reason, even after hearing “Stop!” you just assume you can bike-waltz on through the blocked-off streets of NYC to get you and your tote bag — of, I’m guessing, trail mix, overpriced water, some Dave Eggers book, and artisanal licorice because you “deserve it” — home all safely as the president’s motorcade is about to roll by. Well, that’s not how the world works, buddy.
