Elite FBI hostage rescue team and Las Vegas police trained for high-rise active shooter incident using helicopter sniper prior to massacre

An elite FBI hostage rescue team and the Las Vegas Metropolitan Police Department trained back in 2011 for a high-rise active shooter scenario much like the 1 October massacre in which a highly-trained FBI sniper made the proverbial kill shot by striking a rubber dummy that was placed inside a broken hotel window from a tactical helicopter that was hovering over the strip, according to a new report published by the Baltimore Sun.
