This post contains a video to introduce Christians to the YouTube site, Christian Warriors. Creator of the site, Keith Graves is a former law enforcement officer, 30 years, and a Christian. He collects information from across America about violent events that occurred at churches. He also provides tips, and training in firearms; he explains events in terms of what might have been done to correctly deal with shooters…. That is, he helps to prepare church security teams, that many churches are implementing these days, such that they might function more efficiently.
