Of greatest concern: Evidence from several thousand criminal cases may have been damaged or destroyed by polluted floodwaters. The feds are sending in special teams to help with recovery efforts. But even if evidence is still in usable condition, officials are unsure whether they will be able to locate witnesses who have "scattered to the wind."
Under any circumstances, having to dismiss charges against accused murderers, rapists or other violent criminals is embarrassing--whether in corruption-prone New Orleans or any jurisdiction. It could also prove to be downright dangerous.
