Gun sellers say they're losing business because the Oregon State Police are not acting fast enough on background checks.  Doug Raff, owner of Guncrafters in Salem, says over the past several months, he experienced difficulty reaching the Oregon State Police to perform gun checks.  A bill in the Oregon Senate would put background checks back in the hands of the feds.  Opponents of the legislation say the State checks reduce the chances of guns getting in the hands of criminals.
