Albany The effectiveness of security at the Washington Avenue Armory is again in question after seven people were injured there during a rap concert early Saturday morning. A video of the incident released on the celebrity gossip website TMZ showed members of the crowd picking up barricades and throwing them at each other while performers on stage yelled through the microphone "They're giving them hell right now!" TMZ posted the video because the concert's main act was Migos, an Atlanta-based rap trio that had a minor popular radio hit in 2013 called "Versace." The Saturday incident, which resulted in six men being stabbed and one woman being beaten in an Armory bathroom just after midnight, comes after the Armory and city battled for a year and a half over whether the concert venue could host dance parties.
