Pkg with contraband was intercepted, documented, all needed warrants secured. Pkg is delivered while the house is staked out by LEOs. Sometime after delivery (a day later, iirc) they bust in, find the pkg, and arrest. The pkg was sitting just inside by the door, unopened. Defense argued “my client knows nothing about this unexpected package. Who’s to say the sender wasn’t framing the recipient?” So he obviously got vindicated.
So there’s a game of timing. Recipients need to be given the chance to open the pkg and react by calling the police. Not sure how it goes if you consume it immediately after opening and burn the box. Certainly the wrong move is to open it and let it sit around open.
