Cant really say too much without sounding racist, which I am not.
I work with a totally diverse workforce & the devout Muslims I have spoken to are disgusted by the actions of these two men.
I am sure that there will be repercussions from this but it will more than likely be aimed at all the wrong people.
Seek out the extremeists and deal with them in a way that they cannot cause any harm, if that means shooting the f###kers then so be it.
