My beloved brothers in Islam,
I understood your point perfectly well the first time.
What I am saying is that the Imam, the committee, the local community is contradicting your point i.e. they said that this person clearly had feelings towards ISIS. He clearly displayed anger and resentment towards those who opposed ISIS. He was so angry at refutation of ISIS that a person had to ask his son to be present because he thought he may get assaulted!
All I am saying is that if your theory is correct then the son of a Muadhin of a Masjid is well known and community should easily support your theory.
In this case, just like the Mohammad Sidique Khan your conspiracy theories are being contradicted. I mean the brother-in-law of Mohammad Sidique Khan is on this forum who contradicts conspiracy theories about his own family.
So your theory is being debunked by people who knew this person...
