I really like this idea which is beneficial to both the sender and the traveler (transporter). We get to send stuff to our loved ones and the person traveling gets to make some money. However I have one question. How do you protect a person carrying packages from being made to carry restricted goods from people with ill intention and putting the traveler in trouble. Lets say I decided to carry somebody's laptop to make a small amount and the person whom I received the laptop from had decided to put restricted substance inside the casing. I know this is far fetched scenario but there is always a possibility. So how is a traveler protected?
