So hang on then Jake, this officer, is he a British subject or not? Because if he is, then your argument that "he's got Lebanses family" just shoots in the foot the argument I usually use to the "hang em high, send em home" brigade that want to get rid of immigrants. We say "Ah yes, but he IS Bristish", which is true and valid as far as I am concerned, now are you having it that he may be British but he has Lebanese family , therefore he's unfit to do his job properly? Because if you are then that's an ugly can of worms and one which will blow up in the immigrant poulation's face if it's used.
It's rather like my brother becoming a member of the PCNI, and then refusing to Police the streets according to British law because I personally don't recognise it. The whole thing is absurd, and if it's allowed to prevail will just cause further division.
Now a positive story would have been a Muslim officer protecting the Israeli embassy, or a Jewish Officer protecting a Mosque, sadly no-one seems to get the gist of that and if we don't hurry up soon, it's all going to get a whole lot worse.
