Well Andy, I'm sure you'll understand more than most.
On my part, I think the points raised in that link are valid.
When you consider what it must be like out there, then you consider the huge complexities under these so called 'rules of engagement', it's just way outside the comprehension of most of us.
For me that article makes sense.
I can just about imagine what it's like under in those circumstances when suddenly it all goes off. Who can really say exactly what happened and in what sequence etc. Decisions get made almost instantly and following the automatic reactions of military training.
At the end of it there is a fatality.
Then the politics begins. And that's where my understanding fails me.
Politicians can't even pin down exactly what happened between an MP on a bike and the police.
