That's not what I said. I said that police should be able to do their work without resorting to lies and deception.

Also, notice that GP said "suspect", you said "criminal". Huge difference.

They manifestly cannot do their work without resorting to deception. Virtually all policework above the level of street patrols turns in one way or another on some flavor of deception.

The counter example that comes to mind is a detective who gathers physical evidence in order to convict a criminal. Where is the deception there?

Does this mean you're also against undercover agents and informants? What about things like bait cars?

Bait cars, drug stings, and the like always seemed way too close to entrapment for my liking.

Agreed on second argument.
