I can't grasp this concept. There's no way that you can make a drop that isn't connected to you at all. Some way the package has to get to your hands.
First of all, I think it's safe to assume that if you feel the need to use a drop you're probably ordering more than personal amounts.
If you're in situation where you the person who receives the package contacts you to pick it up, and police to a CD, there's no chance in hell they're going to jail for you. They'll tell the police they're receiving it for a friend and set you up. Absolutely no chance of plausible deniability.
Or you're shipping to some vacant house and just grab the package as it sits on the door. Again takes limited effort for police to stake out the house and if you're ordering bulk amounts you can bet they'll dedicate the resources. Don't you think they'd kill to get the headline: "Los Angeles police capture drug smuggler".
Can somebody help shed some light on "drops" and how effective they really are at keeping you safe?
It helps with seizures where they don't bother to do a controlled delivery, which happens the vast majority of the time. You just write off that name and address and order to somewhere else without worrying that your name is on a list somewhere and that every piece of mail coming to your house is being examined.
