Yeah, I know, that show will be awesome. I can't afford it either, but I have talked with several who go twice a year. That is a lot of firepower to play with. Now as to your video clip, I think it should be mandatory for news broadcast to show day/date time stamps on screen in the actual broadcast. This is one of the early (and wrong ) broadcasts. At last count it was AR-15 and two 9 mill pistols went inside, and the AR was used to kill. One of the pistols was used to kill himself, when the cops showed up. The weapon found in the trunk was NOT an AR-15. Watch the video of the cops clearing rounds. they are working the side bolt lever. (AR-15's do not work this way) their bolt is on top and behind. Also watch as the rounds flip into the trunk. That weapon is a simi-auto 12ga. shotgun. You can see the shot shells fly. The problem with these web copied broadcasts is there is no continuity.and the labels simply show when they were posted, not when they were live. But thank you for posting it.
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
