Dept. of Homeland Security Manual: Section 5, Article 2C

Regarding well educated Canadians from the praries with good jobs and proper identification and paperwork requirements completed, DO NOT BE FOOLED. In a recent study this demographic has proven to be the number 1 trafficker of illegal narcotics, followed in distant second by Columbians in boats who don't speak English and have no identification.

One common tactic these groups of Canadians have been known to employ is to package their household goods in clear plastic containers, thinking that the fact that you can see everything inside will prevent us from opening the package. Again, STAY VIGILANT. As soon as you see this behavior, lift the package above your head and throw it across the room, making sure it lands on it's corner, breaking open and allowing you to inspect the contents that could already see from the outside.

If they ship a computer, DO NOT BE FOOLED. 92% of all drugs and weapons entered the US last year inside the Apple Emac. To make sure it is a computer and not an empty case with drugs or weapons inside, DO NO PLUG IT IN AND TURN IT ON and DO NOT USE SNIFFING DOGS. It may blow up. Instead, rip the back off with a crow bar.

Also, make sure you do a good job of this because we are charging these "Canadians" several hundred dollars for these containers to cross the border and we have a reputation of security and understanding to uphold.
