Agreed
That part I can't answer. To carry out a controlled explosion they would need to enter the vehicle. Wouldn't this enable them to make an accurate threat assessment?
Can we then assume that there was a genuine threat?
I didn't say it was in the middle of nowhere.
I was simply emphasising that there are two ways to neutralise a bomb. One by blowing the thing up (in a place in which it is safe to do so) and two by disabling it by more 'technical' means
I would imagine they judge each case on its particular merit. Blowing up such a device in the middle of nowhere is going to be far more practical than doing so in a built of area.
Yes but the key word is controlled. Rather than waiting for it to potentially go off (at any given time)they cordon off the area and then in this case blow up the van. The threat is then dealt with and normality can be resumed sooner rather than later.
