Exactly. They would need to:

#1 find it.
#2 decide if it's enough to bother with.
#3 trace it to you.
#4 put together a task force.
#5 prove you ordered/requested it.
#6 make sure you have possession of it.

Then they could bust you. However, I don't think too many people would be dumb enough to have such things sent to their own home, let alone sign for such a delivery. Just MHO.
