Not surprisingly, it happened at a college. This photo kind of makes me miss my days in college, although I don't remember anyone scaling the library while draped in a flag.
I guess we just weren't that patriotic at the University of Arizona. Here's some more details from an observer:
Collin Czarnecki, a junior journalism major, witnessed the scene from his Eddy classroom. He said that the caped man rappelled with a rope off the back side of the library and tried to flee by bike from a motorcycle policeman, but had his cape caught in the spokes and failed to escape on foot.
