Yup,

A) If the US had an extradition treaty with Syria then I owud expect it to be observed in both directions. it might sober a few people up if they knew hacking some Syrian's computer could get them shot. Of course, the UK will not extradite people if they face the death penalty so the maximum you could get for hacking Mustafah's Halal website is life imprisonment. Should clean the internet up quite nicely.

B) Again, if this were agreed between both countries to be an extraditable offence then, yes I would expect that. Of course, with the USA considering freedom of speech to be so important then such an offence would probably not be extraditable in which case an American would be free to say what he wants. If, however, both countries have decided a particular act is an offence in both countries then offenders should be extradited to the country where the damage has occurred.
