Maybe I am biased, but I still like my keel-hauling idea! But I understand that not everyone is as willing to go to that length, but whacking them in the most expeditious manner possible and in a manner that ensures the safety of our people would be greatly appreciated and I think prove to be the most effective method in dealing with this ilk.
At first I thought you said - expositious - you know, like sewing them in a pig and parading them ashore.
