Abid Naseer 'should have been charged' by CPS
Former and serving police officers say the Crown Prosecution Service (CPS) was wrong not to charge Abid Naseer with planning a terrorist attack at Manchester's Arndale Centre.
Naseer, 28, was found guilty by a US court on Wednesday of being part of a trans-Atlantic al-Qaeda conspiracy.
The CPS said the admissible evidence was "very limited".
BBC North West Tonight's Clare Fallon has been following the case.
