The debate on whether or not "sting" operations are entrapment has been around for years. I don't really have a problem with them if the cops are posing as buyers of illegal goods or services because nobody is forcing the sellers into doing anything they weren't already going to do. But when it comes to cops acting as sellers of illegal goods and services it gets pretty dicey, if you think about it. Anybody can be talked into anything if you're a good enough salesman. Tempting people into breaking the law where as they may normally never do anything wrong in their lives is a pretty dark road to start down.
