The consequences might have been devastating.
CCTV footage captured the moment a heroic security guard stopped an individual armed with an AR-15 assault rifle from entering a drug treatment clinic in Buffalo, New York, on November 10. Police suspect the attack is linked to a drug case and a possible settling of scores.
Security footage taken outside the clinic shows the two guards wrestling with the perpetrator, Jeremy Griffin, 48, on the ground while two bystanders helped him grab his assault rifle.
Officers report that several bullets were fired during the brawl, but no one was injured.
