Someone'll do it Steamwake, probably the Right version of the Left Loonies who said that 9/11 was an internal job.
Still, elections are a usual time to try things like these, lots of people about voting, set off something at a polling station, etc. Works particularly well in places like Afghanistan and Iraq with car bombs. I'm surprised that America hasn't seen more of them, they've been a favourite terrorist weapon for years, be they Afghani or Irish terrorists.
I'll be interested to see just what was in these packages, no explosive material it would seem but a white powder...anthrax? Or Coke?
