"The amazing claim that "There is no terrorist "hot spot" in these islands" is obviously impossible to prove."
The burden of proof lies with the accuser Nigel
If there are "hot spots" it would be possible to prove there were - that's what "hot spots" are
Nobody argues that there aren't potential terrorists.
The suggestion that there are identifiable areas or communities is disconcerting nonsense - much used by racists, anti-immigrationists and Little Englanders

Until the removal of Abu Hamza the Finsbury Park Mosque was a 'hotspot' for radicalisation, and I expect the necessary forces kept close tabs on it.
Since that time, it has, unfortunately, become a target for others.

If you believe there are currently no 'hot spots' I believe you are deluding yourself.
