Its sickening there are people out there capable of carrying out an attack like this.
A professional hit like this would have been carried out by a team of killers, probably 3 or 4.
Whats REALLY scary, is these people are probably working for and trained by a government.
The funny thing is there is already attempts being made to spin this into being the dead guys fault and linking him to al qaeda, and make him out to be some sort of evil mastermind trying to carry out a nuclear attack or sell nuclear secrets.
