His Mother is British and your court system is sort of, too
Since his Mother was born in Wales, and Manning was even conceived in Wales - important if you subscribe to the belief a person exists at the time of conception.
Still, even if Manning isn't British (which he could easily claim) ordinary, decent morals require that prisoners be treated in a humane way. Even the guys down in Guantanamo have it better than Manning because the thick sculled Marine regime in Virginia have pre-judged him OR want to reduce his mental capacity to such an extent that he will be unfit for trial.
The U.S. screams loud enough when one of it's personnel get banged up in Korea or VietNam but Manning, remember, is one of your own. The U.S. is sticking it to their own people which makes the Marines Corps as despicable as the captors of Americans, if not more so. Of course Manning's abuse is a great moral booster, too, knowing that your government is capable of permitting this to happen.
This will enable the aforementioned thick sculled Marine regime to disown him and say he was accepted by mistake, etc.
Hell, some bent characters might even say that's what happens when you let gays at the secrets - seeing how the Marines are so enamoured with people of alternate life styles.
The fact is the U.S. government is dumb. It gave over 3-million people clearance to view these 'secret' messages that were little more than what people write when visiting another country. There have been no 'secrets' revealed unless you call the murderous bastards flying the helicopters that were used to serially murder two Reuters reporters and a bunch of unarmed civilians featured in the leaked video.
No other country has suffered such embarrassment because (a) None is dumb enough to give so many people, in so many places, access to material that is superfluous to their job; (b) over use of the term 'secret'. It would appear that only toilet paper escapes being given a secrecy rating.
Whilst not many in the U.S. can see it at this time, Manning has done everyone a favour (if he did in fact leak anything) as (z) the U.S. has reviewed it's security procedures; (y) has implemented some form of security on computers having access to restricted material; (x) has demonstrated to the diplomats that they are little better than gossips.
The other beneficiaries are other countries who now realise, if they didn't before, is that the U.S. doesn't honour agreements, it is two-faced and even stoops to collecting DNA from other diplomats with whom they come in contact and plays dirty.
Two consecutive U.S. governments, of both political stripes, have now voted to deliberately break the terms of The Constitution which goes to show just how amoral the politicians and government is - and they deem to tell other governments how to run their operations!
If you went to school in the U.S. or even joined the military you might recall just how many times you vowed to uphold/observe The Constitution - almost daily. Sort of diminishes the worth of all those pledges to being little better than hot air.
P.S. I carry a U.S. passport.but am too embarrassed to use it.
