The case of Californian John Patrick Bedell comes as little surprise to 9/11 Cultwatch.
Take a damaged individual, encourage their paranoia, construct a world view that centres on both weakness and an over powering system, then having lit the fuse, step back and watch them explode. Bedell, a 9/11 'truther' travelled from his home in Hollister all the way to the Pentagon, where on 4th March he opened fire on guards outside the military complex, before being shot himself.
There will be others.
Future incidents like this are as good as guaranteed and those in the 'truth' movement need to think long and hard about what they say, what they do and how they say it, especially when dealing with individuals with mental health problems.
Sadly, the chances of such responsibility being displayed by the likes of Alex Jones, David Icke or Webster Griffin Tarpley are extremely low.
