The 2003 Extradition Treaty between America & England works very efficiently for both countries. Since it’s review the standard of evidence required for an extradition has been lowered.
There is no need to have a prima facie case in order to apply for the extradition of your ‘suspect’ and bag your man.
The only problem with that is what happens when someone suffering with a learning disability is suddenly transported overseas and into the arms of a judicial system he knows little about.
Most people would display no little concern at the idea of an autistic person (however mild his autism ) being forced to defend himself in a foreign court. Especially when the charges concern allegations of terrorism. This is what has happened to Talha Ahsan.
May be the allegations against him can be successfully substantiated; but when you bear in mind the case of Shaker Aamer, held without charge and without being freed in 11 years it makes you wonder.
Talha Ahsan, a British citizen, could also have been tried in England on home turf with much easier access to his family. That wasn’t permitted to happen and you have to wonder why.
