Then there's the case where the police found drugs in the mail, but let it be delivered anyway. When the homeowner (the mayor of the town, incidentally) came home and brought the package in, they attacked, killing his two labradors (one while it was trying to run away).

After, even though the police had the drugs in their hands when they found it in the mail, the chief said, "We′ve apologized for the incident, but we will never apologize for taking drugs off our streets....Quite frankly, we′d do it again."
