Blind prejudice against a news source when they link to a primary source (http://www.khou.com/news/texas-news/Texas-teen-charged-with-...) as well as name names that can be trivially searched for with zillions of hits (e.g. https://www.google.com/search?q=Justin+Carter+threat) is not constructive.

I googled the term "Justin Carter texas teen jail" and got a whole lot of links from other websites and thumbnail of a youtube video of what looks like a local tv station covering the same story.

I haven't looked into it further but if all you had to doubt the story was "Reported by Daily Caller?" I think that should be sufficient.
