Greg Davis is a friend of mine. He and his colleague, Bryan Daly, produced a film about the rise of jihadist Islam entitled: "What the West Needs to Know." It is a disturbing but well-done and well-researched film. I recommend it.
For a quick take on what Greg and his colleague are doing, here are links to two short interviews, one that Daly did on MSNBC and one that Greg did on Fox.
"What the West Needs to Know" can be ordered here.
