1) clubs hire off-duty cops bc they shoulf KNOW the law. Knowing the law means that...

--> they should know that beating a handcuffed customer in the face while he's choking on a dumpster shouldn't happen
--> that they are job is to remove them from the premises ... not interrogate or torture them out back
--> the club should hold regular meetings on what is allowed and what is not for their security staff

** on a 2nd note, unless you are going to jail or having sex I think it's illegal for a bouncer to handcuff you - but I will check on that.
