Do undercover cops sin by lying to the criminals they intend to catch?

The first sin on earth was a **lie** perpetrated to Eve by the devil in the garden of Eden, where the devil lied to Eve by saying that >Ye shall not surely die, but shall become like the gods knowing good and evil Now scripture is authoritative on lying and condemns it because it's equates to bearing false witness against your neighbor. This is where my question comes in, when undercover police agents **lie** to the criminals they infiltrate in order to catch, do they sin? This is because even though they lie, they do something Biblically wrong for a long term good objective, to out a bad person behind bars.
