After reading everything from here at FR, the various news outlets on cable and tv...and my own background as a business owner and private investigator, I'll just note the following for right now:
There is no such thing as "coincidence".
None of the stories being reported right now "match up" with any available data to support one version over another. The families public statements are at odds not just with the Federal Government, but also with various media outlets, statements from Berg's friends both here and abroad.
I keep coming back to the theme that this is another wacko Johnny Jihad wannabe. I have nothing to support that gut feeling to date....but I also know every time I've ignored my gut feeling I've regretted it later.
