I've been thinking a lot about a PO Box. I've read all the info I can find (the search button sucks, but Google is my friend). Still, I don't see how the pros outweigh the cons. So I'll tell you why NOT to use a PO Box. You tell me why I'm wrong (because serously, I really want to know).
Getting a PO Box means the package is in the control of the USPS that much longer. The lobby is probably filmed 24/7. The box is opened under my license, so it's 100% tied to my name. If they ever discover a package, it's 100% mine, and they know it.
However, if I just let the mail come to my front door, then I see it as MUCH safer. Whenever I have a package coming, put everything illegal and place it in a go bag. That go bag is taken somewhere safe. Now there is NOTHING in my house that shows I'm a potential DNM client. Not even Tails or the laptop I use it on. I'm just a regular person. That package mailed to me? I've got nothing to say, I'll get a laywer. The lawyer will make the case for me that someone else mailed the package and was going to take it before I ever saw it. It's not mine.
If I the package come to a PO Box, I don't get to play that scenario out. I don't really know what defense I come up with.
So, make the case for me. Why should I get a PO box?
PO Boxes provide safety from nosy roommates and some anonymity in that vendors don't immediately have your home addy. While you are technically right that a pack is sitting in USPS control longer, that's a very loose definition of what "control" means. Realistically it's sitting in your box and they prob won't give it a second glance. So it's a very loose definition as it's not truly in their hot little hands that entire time.
It's true they'll have you on video picking it up. I posit that it doesn't matter for anybody except maybe those getting bulk for distribution. The only time it matters is if they are busting you and in that case they'll have evidence of you accepting the package either way. More than likely you'll be busted within minutes. For a distributor where they may let you take the pack and not bust you right away, this may make it easy to show you did get it and never return it. For a personal buyer this won't matter. A bust will go down within minutes either way. For a distributor even then it may not make much of a difference bc if they are letting you receive the pack and stew on it, they are watching either way
The short of it is that a PO Box is not better or worse necessarily than a normal addy. It has it's pros and cons and most have nothing to do with legal stuff. It's more reducing the risk of package theft.
In your specific example your go bag is not relevant. Regardless of where the pack is delivered, LE will not lose control of that pack. They'll know where it is. Prob bc they bust you within minutes. You are making the assumption LE will give you time to move the goods. They won't. Having a clean house is important in both cases. Possession of the pack will give them a search warrant usually. A PO box doesn't prevent that unless you have it in someone else's name or something which can be worse. You'll get a boot to the throat in no time in both cases. You'll be afforded the same defenses you have in both cases. I believe it plays little to no difference. LE isn't going to let you go a few days without watching that pack.
There might be a very narrow scenario where what you say is valid. If LE didn't perform a CD at the time and got info much later that you received illegal shit. At a PO box they'd have a video of you getting a pack. At home they wouldn't. But this is an extremely narrow case that is not the case 99% of the time. Bottom line if they don't do a CD at time of delivery or was watching the pack, they have nothing but maybe a knock and talk
