(Portland, OR)  --  An Oregon newspaper is documenting five cases that suggest the Saudi government is helping its citizens avoid prosecution for crimes they committed in the United States.  The Oregonian says two accused rapists, two suspected hit-and-run drivers and a man who had a large amount of child porn on his computer have all disappeared before facing trial or sentencing in Oregon.  All five suspects were young men studying at Oregon colleges with the help of the Saudi Kingdom.  In four of the cases the newspaper says the Saudi government posted bail and possibly paid legal fees.  In one of the hit-and-run cases a high school sophomore was killed.  In the other a homeless man was critically injured.  Three of the suspects were forced to surrender their passports, but that didn't seem to keep them from leaving the country.
