"Justice cannot be upheld through recourse to methods which abandon its principles"

The only person convicted of involvement in the 911 attacks has won a retrial. Why? Because the US had refused to allow the German intelligence services to share possibly exculpatory evidence.

The September 11th attacks were terrible, but that does not mean that we should throw justice out the window when punishing those responsible. Suspected terrorists deserve the same legal protections as everyone else. Fundamental to this is the right to a fair trial, to review the evidence against them, and question their accusers. Compromising on these rights results not in justice, but in judicial lynching - it is literally destroying western civilisation in order to save it.
