It probably has to do with the weapons used and if they were legal.
Posting this video brought this hassle on the guy who made it.
I am trying to find the video..I am wondering now if it was a full auto rifle after reading a few articles online...Some say the typical "Military Style" which usually is MSM speak for semis, but another article says it is was a (full auto) M-16. Then again most media outlets don't know the difference anyway.
Looks like the vid was deleted from myspace..I'll see if I can dig it up.
I found a video but I don't think it is the same one. The one I found is some dude and his buddies lighting up a Koran with some civilian semis and a 12 gauge. It says on his website that the FBI was investigating death threats against HIM and his family by a terrorist organization.
The vid I found is from June of last year.
