It is very surprising that a PHD enginneer will volanteer to become a suscide bomber,as many uneducated and unemployed may have ben convinced for that job.
And every one knows that a scintist will first test the prototype several times before doing the actual opereation.
Come on illitereates are blowing cars and trucks in Iraq and Afganistan.It is something impossible for a highly educated enginneer to not blow the car as it is a simple task,as the only difficulty is getting the car nearer to the target,which seems to be highly unlikely with the security conditions prevailing over in Uk these days.
