If you are pursuing a suspect you believe to be carrying an explosive device would it be fair to assume that the device is primed?
In which case, I wouldn't want to risk the remotest possibility that the suspect could denonate if kept alive, taking you, your colleagues and a lot of innocents with him.
A very dramatic demonstration to the perpetrators that our security services mean business.
All over every front page in the world, I imagine, they will see thier failure.
I assume that if this guy is a failed suicide bomber then he won't now be in Paradise with 80 maidens at his beck and call?
Shame, he's really missed out.
