Free speech and all that. However, one hopes we aren't as stupid as we seem to be and that the FBI took lots of video and followed them all home. Here's hoping they also carried out a few 'trash' searches and hacked into their internet activity. If they pull a few threads, the whole sweater might unravel.
Maybe I clicked the wrong link, but this D.C. meeting on Iran with Sen. Kay B. Hutchinson speaking seemed focused on democracy and freedom for Iranians. If there was some other meeting with terrorists milling about, soliciting funds, new members, I hope the FBI took notes.
