If something like slavery, child abuse, cooking meth, etc. is happening, you need to address it with whatever means you have and not worry about political niceties. Safety of individuals from terrible outcomes must always trump being polite and sensitive. For lesser problems, say noise levels, garbage disposal, minor traffic violations, then you need to be more sensitive, aware, slower to react, meet with community leaders etc...but for some things you have to react swiftly and surely. You can not leave people in slavery or horrible conditions because of any ...well for any reason...you just can't.
