Yeah, I've never given much weight to refusing to sign or putting a "return to sender" note on the package. If it is in your home, and especially if it has your real name on it, you will most likely be charged. A fake name adds some plausible deniability. I know of one person who had a package of subscription opiates intercepted. It was not a large quantity, not enough for a controlled delivery. But LE did a knock and talk, asked him about the package. Since he used a fake name, he claimed it was a former roommate who had moved out. The cops may have known he was lying, but there's nothing they could do. Wasn't enough evidence to prove he had knowledge of it in a court of law. I have been told about another person who had some marijuana intercepted. LE also did a knock and talk, but he admitted it was his and got charged. You need to eliminate any evidence that you had prior knowledge of the package. Obviously either don't talk to LE (don't even be home) or vehemently deny all knowledge. A fake name is better than a real name. Passive delivery is better than taking a positive action. If you live in a place where mail will only be delivered to names registered on the mailbox, that makes things more difficult. In that case, consider getting fake identification and a PMB.
