Good, I'm glad to see that you are trying to contribute. Start with thread one and go from there. While you are educating yourself, check SmokingGun.com and look for the Al-Quada handbook. There are in-depth plans in their own words; where blowing-up bridges and blocking thoroghfares are laid-out.
Please excuse me while I look for relevant information to contribute. Especially considering the warning yesterday from Homeland Security, and the FBI.
i've read all the threads, friend, and everything you've cited. thanks for patronizing me, though!
