Just a point here, at least one of the "heavies" works as a freelance doorman (bouncer) and part time as a car clamper, so much for "voulenteers". Does anyone think the party bosses were unaware of the "security arrangements"? How does TB "not being in the confrence center then anyway" (TB's words on BBC) have any relevence to the issue. I remember when a politition would love a good heckle, just think about Skinner's assides in the commons!
Power corrupts, Ultimate power corrupts ultimately!
