"One policeman sacrificed his life by holding the suicide bomber to his body. This allowed the remaining security forces to empty the surrounding areas of traffic and cordon the area off to save the lives of numerous civilians."
Could be the Officer was preventing him from doing this. Yes there could have been/probably was a second person with a remote detonator. We'll never know exactly what happened, all we know is the Officer sacrificed himself to save others.
Here's a toast to our wives and to the women we loved. <pause> May they never meet.
The M1 Garand rifle is the best battle implement ever devised by man.
