but the offenders are just What?

Whatever the advertisement or promotions made by Dubai, did it ever promoted such actions?

Precisely the law of NO HARM NO FOUL. No one offended, no one will complain. No one is directly saying you can not do it, but just make sure you won't be caught!

We always say that there is no CLEAR CUT policy, so play SAFE! Why tripped the line of what is acceptable and what is not?
