Rahman described killer Mumtaz Qadri as a “true Muslim” after he was ­executed in February for murdering politician ­Salman Taseer, who ­raised questions over Christians being persecuted by Pakistan’s blasphemy laws.

Using messaging service Whatsapp, Rahman wrote: “A true Muslim was ­punished for doing that which the ­collective will of the nation failed to carry out.”

Mosque leaders last night said in a statement: ­“Community leaders, including Imam Habib Ur-Rahman, have in the past consistently spoken out to condemn in the strongest terms, radicalisation, extremism and terrorism in all shapes and forms and will continue to do so in the future.”

The apology came after Muslim leaders held ­emergency talks.

The statement added: “His comments were never intended to condone violence but were intended to refer to resolution by passive means involving due process.” Unquote.

And....
One brother told the Mail on Sunday that the family is living in terror that a fanatic might repeat the crime, that police have said was “religiously charged”. A 32-year-old Muslim man has been charged in relation to Asad’s death.

Some will remember the Glasgow Airport attack in 2007...

which was carried out by highly educated people. London's 7/7 bombers (July 2005) were "home grown" and often regarded as "nice people" before their atrocity.

The UK is not alone in poorly assimilating some Muslims. It was reported recently on UK TV that about 95% of terrorist attacks on European targets are prevented and "thousands" of people are involved to some degree.

There is some evidence that things are calming down in the UK. As I recall, it took until 2008 or 2010 for a British Imam to condemn (without any equivocation or ambiguity) the 9/11 (2001) attack in New York. Now, condemnations are much clearer and quicker. On the other hand, we are told that more attacks are more or less inevitable.

I doubt there will ever be an end to such violence without an end to religion. The superstition about an afterlife and the tribalism are too attractive to some violent people who are both devout and alienated. The concept of blind religious faith is a factor too. And we are currently saddled with a crop of particularly reactionary Tory politicians and a PM who proudly 'does god'. He has said "'people of all faiths" while often failing to add "and none" when that would have been appropriate. They have actively promoted religiously denominated schools and defied a high court ruling that "Religious Education" in schools should include non-religious world views.
