Entrapment is usually a horrible thing to do, but it is unfortunately standard practice with local police as well as the FBI. Would you agree that those agencies should not have technical services provided to them?
Entrapment as defined by the law is illegal. However, what a lot of these agencies do is not strictly entrapment as defined by the law, and as such is very legal (unfortunately). I'm betting the majority of terrorism cases in the US since 9/11 involved what looks like entrapment, and I believe pretty much all of them have held up in court.
So my question remains. When all of these agencies are practising legal entrapment, would you agree never to provide services to them?
