Can muslims take control of a city like London?

Chelsea Barracks is the second home of the SAS for reasons that us mere subjects can only guess at. The Met (London Police) can barely get a token contingent of Asian heritage (that means brown from the sub continent in the UK).
The idea that the Metropolitan police suddenly becomes infested with Muslim terrorists (who are of course not white) is not even faintly ludicrous, it is full tilt ludicrous.
Welsh guards regimental home is(current)Pirbright 36 miles from central London. I doubt there are many black faces in the Welsh Guards let alone brown.
2 Para, Colchester, 67 miles from Central London. The list goes on. Grunts come from the working class and any infiltration is very unlikely due to the very great majority of white and some black faces.
If I went on this would become a wall of text listing military garrisons within an hour of Central London.
I take it the OP made the post to get a rise from Muslim haters or garner support for some Muslim bashing on the IMDB.
Personally I could not give a damn. I live in a well protected country, more people die on the roads in a month than have been murdered by religious nuts.
In America more kids are accidentally killed by their parents guns than people murdered by scum in the UK.

Could be. Because the loose immigration policy, Muslim population has reached 25% in major cities like London and Paris. They have the man power and can take over the governments at any moment. Thanks God we have very strict immigration laws here. If I were President, I will open border of Mexico because Mexicans are not Muslims. The percentage of Muslims in US will be reduced.

You are a racist. Just thought you should know.
