Whether or not the requirement is met in Assange's case is to be decided by the court. There are certainly laws in the UK that prohibit hacking. Anyway, you are wrong in general about how extradition works. People are often, for example, extradited on murder charges.
That's a legal question for the court to decide. I wouldn't say that there's anything "clear" about it.
If you actually read the article on the McKinnon case, you'll see that extradition was ultimately refused by the home secretary - not the courts - on largely compassionate grounds:
"Mr McKinnon is accused of serious crimes. But there is also no doubt that he is seriously ill [...] He has Asperger's syndrome, and suffers from depressive illness. Mr McKinnon's extradition would give rise to such a high risk of him ending his life that a decision to extradite would be incompatible with Mr McKinnon's human rights."
When I said I was being gay I meant I was both giving and receiving homosexual acts while shopping in Saudi Arabia.
Oddly, being gay is a crime in Saudi Arabia, but only committing homosexual acts is a capital offense. I would make a joke about the type of kangaroo court that would convict me of being gay, but it’s sad because they exist and people are convicted.
