Most Arab countries have a lot of immigrant labour (e.g. UAE 90%), and if you are on the receiving end of their legal system I can’t see why they would treat you much better than say a poor immigrant. Even if white, I am not sure you would get any privilege points, and instead it might work against you (think English chavs or German dicks in Majorca).
In most countries I have visited, visitors get away with a lot, because they want tourists, and because the tourists are relatively wealthy. In the UAE you are relatively poor compared to the citizens.
