"He's not an immigrant - he was born here and lived a perfectly normal life until 1999 when he decided radical islam was for him. "

Ah OK thanks I never knew that

"I am not defending his alleged actions or associations, but when he is British by birth and insufficient evidence exists against him to prosecute him, he can not be refused entry simply because he may hold anti-British views or consorts with others who do."

But he did serve time in Pakistan yes? if that is the case and the crime involves terrorism in the UK surely the Home Office would have the option to revoke his UK nationality assuming he has dual citizenship in Pakistan of course

I'm not sure if the UK has a law that would allow them to revoke citizenship...I know they considered such, but I don't remember if it was ever passed into law.

The law in Pakistan is somewhat more flexible in terms of the burden of proof required for guilt to be established than in a British court. Legally it is not possible to revoke the citizenship of someone British, born in Britain and of British parents. I strongly suspect that if the home office have not charged him, it is because they have insufficient proof, or they see more value in observing his next move.
