Police officers climbed the Brooklyn Bridge on Fri., July 25 to investigate the sky-high crime scene that dominated New York City headlines last week after intruders swapped the two American flags atop the landmark for two white banners. Although conspiracy theories surrounding the stunt took over social media shortly after the news broke, police are still working to narrow down its list of suspects. Investigators have reportedly taken DNA from several large aluminum pans that the trespassers used to cover the lights on the bridge.
