What is the problem over there?

I don't really understand the issue over here. We have an organization whois members are being questioned by the police in hoping that they will feed the police some information in return for money. Isn't that called 'bargaining' or 'negotiation'? I think so. The problem is whether any member will be willing to be the mole for the police. I think it is something for people to think about. Is the police's action morally sound or they are just a bunch of law enforcement officers? You will be the judge.
