I think that the courts tend to lean naturally toward government power in the name of safety, so I think it's a stretching of the law at best.
I agree with you fully Pride. It is a moral and philosophical issue, which are the obvious basis for all "laws." This type of police work is very clearly entrapment.
#1. The police provide the specific opportunity that otherwise doesn't exist.
#2. Since you are committing a "pseudo" crime, you are not actually not committing a crime. Even if you think you are committing a crime, you are not.
#3. The idea that these people are looking to commit these crimes anyway is flawed logic, we can't possibly convict individuals on the idea of knowing what they were thinking. There is a very good chance that they are making decisions based on the proactive actions of law enforcement.
These types of stings clearly violate your God given freedoms as an American, but like so many things, courts have decided what your rights are when they have been clearly defined in the Constitution and Bill of Rights.
