He called it "an absolutely sickening and despicable attack of appalling brutality".
Clearly they represent quite a few Muslims. Al-Shabaab has supporters in Somali diaspora communities around the world. One such community in Kenya was likely the source of at least some of the attackers.
Furthermore there are plenty of British Muslims in Al-Shabaab.
Announcing that what happened in Kenya has nothing to do with Islam is a good deal like announcing that the USSR had nothing to do with Communism.
Cameron clumsily attempts to distinguish between terror and religion. But terror is a tactic. It can be carried out in the name of politics or religion or both.
Terror is not some isolated entity. Its goal is to achieve political ends by terrorizing people. Muslims rely on terrorism because it allows them to intimidate larger and more civilized societies and then force negotiations.
To deny this or to act as it there is some discontinuity between an ideology and the tactics used to carry it out, as if the two can exist apart from one another, is simply denial.

Ordinary Kenyans shoppers are smarter than this politician. From the live feed on Kenya Mall Siege on BBC today
A witness who survived the shopping mall siege said the gunmen were asking people to recite a Muslim shahada (testimonial to being a Muslim - "I testify that there is no god but God and that Muhammad is the Prophet of God"), according to Kenyan newspaper The Standard, seen by BBC Monitoring. The woman said she quickly memorised it with the help of a colleague. "When I mentioned the first word of the Shahada, they moved on. That is how I survived," she said.
Wonder what the above has to do with Islam?
