Recently two Canadians travelling from Eastern Canada to Toronto made a wrong turn and ended up entering the US. The alert border guards detected the aroma of pot and did a thorough search. Result - saleable quantities of pot and ecstacy and two handguns, one with a filed off serial number. This from a country where private ownership of handguns is highly restricted. The upside is they are cooling their heels in a US jail, the downside is they are doing it at US taxpayers expense!
