An entire mall in Burlington, Massachusettes was shut down because two women became alarmed at a man carrying the umbrella in Nordstrom's. They reported it as a man with a rifle. SWAT teams, ATF and customs officials were called out and over 40 police from 4 different townships showed up for the excitement. The poor guy recognized his description on the news and called in to admit carrying the dangerous-looking rain-combat device.
