Preventing radicalisation: Double-edged sword

It’s just over a year since suicide bomber Salman Ramadan Abedi, a 22-year-old local man, murdered 23 people at an Ariana Grande concert in the Manchester Arena.
It was an act of terrorism, just as the IRA bombings in that city in 1996 and 1992 were. Abedi had been radicalised in Manchester, a process copper-fastened on a visit to Libya, his family’s country of origin.
