Never make the mistake of assuming what LE will do mate. If you think they would not intercept and then let through to follow the drugs to help build a case to bring down a larger importation operation you are mistaken I am afraid. Also if you think LE/customs could not open your package and reseal it without leaving any signs of tampering you are again I'm afraid mistaken. I respect your opinion but I should point out that I am not merely speculating in this instance, I know the details of the person this happened too and the charges they face are real, I am not in the habit of spreading FUD.
