This morning, the local NBC station ran 3 hours of live news about a shooting at the main Las Vegas courthouse. According to reports, a lone gunman entered the building and immediately started firing.
Two officers were shot, one fatally. A guard was shot and killed. A marshal was shot and injured. The gunman was killed as well. (There was helicopter video on the NBC channel showing the body of the shooter.)
Below is a video taken by a guy in the area for jury duty. The number of shots is unbelievable (I counted over 50).
Warning: Some adult language is heard in the video.
