dear me, sadly this is the type of person hes up against.
And your point is?
A, let him off he's just some lovable chap who is a bit ill and has misplaced ideals?
B, He's from England we dont do hackers he's just excercising his right to freedom of information?
C, Its only the USA's stuff he hacked, we hate them anyway where's the harm?
Most if not all of the arguments are invalid and deserve no consideration,
He showed the USA the way they were not securing their computers?
No, he hacked and fumbled his way into a place he was not supposed to be, he knew where he was and what he was doing.
He should not be tried in the USA as he has a medical condition?
No he should and can be tried in the USA, if we do not extradite him the USA may in the future deny us the extradition of a US person who comits a crime considered serious in the UK but rather funny in the USA because it exposed lax security in the UK. People with far more serious health issues are tried for lesser crimes and serve out their sentances, you cant make any exceptions, ever.
He did not break in the door/security was practically open anyway?
Just because the door is open or security is lax dose that mean you can go in the house/server/shop/ect ect ect. No, its no less a crime than if you used brute force and smashed your way in.
