Isis

The capture, by a group of Syrian Kurds, of El Shafee Elsheikh and Alexander Kotey - the two Londoners who were in the beatles, a group responsible for the torture and beheading of at least 27 hostages, has bought to a head the issue of what to do with British Citizens who travel to join and fight with Isis. 

Both El Shafee and Alexander have been stripped of their British Citizenship so there is little use of looking towards our government for advice on this. 

We have no proper system in place for dealing with captured Isis Terrorists.  If they are within a war zone they can be eliminated by drone strike whether they are in combat or not. When they make it out of the war zone it is expected that they are treated to a full civilian trial at public expense.  The trials are often helped by the fact beheadings are often filmed and placed on you tube to watched around the world. 
Isis fighters returning to Britain to face trail often would find themselves acquitted on the grounds of lack of evidence or they would only be committed of very minor offences and eventually be free to return to out society. 

It is thought that around 800 Britons are believed to have travelled to Isis territory and 400 have returned. 
Max Hill, the governments independent reviewer of terror legislation has suggested that they can return to the UK to be rehabilitated.   I don't think this can work.  Isis will never disappear.  It will always remain active, an active influencer of the mind it has already poisoned and a continued terror threat. 
The Britons that return to the UK, War criminals infact that return to the UK, need to be dealt with promptly and properly and not through our judicial system. 
We need some innovation for this, a system that respects all human rights.
The victims of Isis live under constant evil so as part of their catharsis they should be given the power of prosecution over their oppressors.
