True, but not as much as the shitheads who pack illegals into a hot trailer and drive them to their deaths.  I have driven for hire and I ALWAYS knew my cargo, as you are required to have shipping papers/bill of lading for what you are transporting.  I was hauling explosives, and radioactive materials, so I know what is required.  This driver was a human smuggler.  He knew what his cargo was. HE AND THE COMPANY HE WORKED FOR IS RESPONSIBLE.  PERIOD.
