Las Vegas police have released the body cam footage that shows the moments leading up to them racing up to Stephen Paddock's room.
The video was released at a press conference and is a compilation of several officer's cameras.
***GRAPHIC VIDEO WARNING***
The body cam footage shows officers in bright vests moving from building to building, using the walls as cover.
In one sequence, it shows civilians confused about where the gun fire is coming from and one officer rushes out to them to make them get down and take cover.
"Hey, they're shooting right at us, guys, everybody stay down, stay down."
In the same conference, police revealed Paddock hid cameras in a room service cart outside the two rooms he rented as well as in the doors' peepholes to keep an eye out for police and SWAT.
