yeah it's very weird.
but they could not notify this pakage one time is out of office, it's assimiled as legal pakage.
Low on customs is not retroactive! but the tracibility of you adress and what you could get, could be achived.
It mean in the fact, than when even they want, they to wait a new pakage, but without presumption, you could be immediatly under arrest...
procuror of "Batton-rouge" have made a arcticle about this in a french magasine.
This modification help the quickness of operation and arretation when they to make it.
but like i said :
Scared about cops or customs???
