They have an interesting tactical shotgun video set as it relates to LE use. No to much actual shooting thou. Other videos too, such as firearms retention.
http://www.policeone.com/ is another good site for general police information. If you subscribe to their rss feed they have some interesting things that come across. They're one of the few things I actually follow on Twitter. Thousands of articles and if you're a law enforcement officer you can register for access to 'leo only' articles, videos, news ect.
