i dont expect the police to be fluent in english.... in a country like Qatar where you find more expats than locals on the road you would expect some basic level of english undertsnding on the part of police.
english is not my mother toungue too but when an expat has ab accident in delhi he speaks to the police in english and not in hindi....
the point is english is an international language is it too difficult to undertand english?
but i think gypsy nailed it with her answer.... it has got nothing to do with the language....
if you get hit by a landcruiser.... its your fault....

I have learnt it the hard way.
