I was just kidding with the UK tourist joke UK & Brit, forgot to add the ;)

There are lots of pro's in Dubai and Abu Dhabi (as there are in Doha) but you can't arrest every skimpily clad woman as a prostitute. Especially since most of them cover up in abaya when they go out to do their business.

In general the police here are concerned with stopping trafficking and busting up brothels, rather than arresting single pros. Same as in most countries.
