But what if...
Although there have been some persuasive comments in support of the "rule of law" come what may, I am currently of the view that justice of a sort _has_ been done. Those who stray on to the battlefield simply have to take their chances.
Another way of looking at the "termination with extreme prejudice" is as follows: what if the same two people had been killed either by action on the part of the Syrian government (which we don't like) or by Kurdish forces whose aims are more akin to our own? Would we expect our government to protest to whichever was responsible that two innocent British lives had been lost? I certainly wouldn't. The two concerned had taken up arms to fight for a cause; the fact that we may regard that cause as thoroughly appalling is almost neither here nor there. Given that their cause sees nothing wrong in beheading anyone who is not to their taste I cannot shed any tears about their demise.
I worry about saying this but our strict adherence to legal process - in particular to the HRA - could well be our collective downfall; before anyone tells me I am fully concious of the fact that saying that opens up a Pandora's Box of potentially unimaginable horrors. Which is the least worst option?
And in any case "shit happens".
