Being of an anarchic -- or Zenarchic -- disposition, I really hate to call the cops. I'd rather, to the extent possible, have people talk out their problems as a community of equals, rather than throwing "authority", with its dangers into the mix.
But when I see two young idiots racing their go-karts on the rainy street, presenting a hazard to navigation and raising the potential for traffic accidents, my choices are 1) let it go, and if an accident is caused, ah well; 2) try to chase them down on foot and, if I catch them, give them a stern talking-to; 3) try to chase them down on foot and, if I catch them, take more direct action, like pulling a wire out of their noisy little engines, or 4) call it in to the BCPD, knowing that not much is likely to come of it but at least I've done what I could.
Please, folks: don't behave in such a stupid manner that I have to make decisions like this. Thanks.
