Orlando Shooting?

At first I thought this might be a real event.  But then it dawned on me – after all those hours of standoff, the place would have been surrounded by local police, swat, and a dozen aphabet agencies.  In addition, fire, rescue, ambulances, and EMT’s would have been everywhere to assist.  Once the shooter was killed, there is NO WAY they would have let people exit the building and carry the wounded off to who knows where.  They would have secured the building, triaged the wounded and removed them in an orderly way.  And NO ONE would have been allowed to leave the CRIME SCENE – because any one of them could have been an accomplice.  The whole premise behind this is absurd. This one FACT assures me that this is definitely a false flag, drill/training event.
