@Los Angeles: First they went through the line scanning tickets, stamping hands, and putting on alcohol bands. Then when the doors opened, they did a quick frisk of ankles and the ribs/armpit area. Then they used the wand for the midsection of the body and you were in.

@Vegas: They pushed through the crowd once to check tickets, didn't stamp. Then they went into the crowd again wanding down everyone. Seriously, if you had something just avoid them, they moved slow and you were in a crowd. When the doors opened, they had a second ticket check inside.

If you were caught filming something inside...
@Los Angeles: They pointed at you and made a scary face. Had a few guys in front not really caring/looking, and a guy on each side.
@Vegas: They shined a flashlight at your camera. Supposedly if you tried enough times they threw you out. They had people constantly looking out for cameras in front.
