As reported at the website, Boing-boing [boingboing.net]:
The "Straight Pride [newrepublic.com]" Parade that was held in Boston in the end of August was just another example of thinly-veiled alt-right trolling. Unfortunately, it also worked. A hateful parade of a hundred-or-so people managed to divert hundreds of thousands in taxpayer dollars into overtime police coverage and shutdown streets during the busiest weekend in the city (Labor Day + college move-ins = hell).
Thanks to WBUR [wbur.org], we now know that that cost included 9,000 hours of overtime work for local police officers—the equivalent of 4 years of full-time policing service. And none of it was officially caught on film, despite the police aggressions [boston.com] caught on social media and the 3 dozen counter-protestors who were arrested during the parade.
