This week's shooting in Las Vegas was an absolute travesty, but it could have been much worse had it not been for the quick thinking and bravery of first responders.
Now, thanks to released audio from police radio, we can hear just what was going through their minds as they dealt with a maniac with an automatic weapon.
As they figure out the shooter is in Mandalay, they organize how to best neutralize him while saving and rescuing the many injured below.
No matter if you are in Vegas or not, if you see a first responder today, be sure to thank them for doing the often times difficult job that they do.
