who thought that feeding dead animals to livestock was a good idea.
Until mad cow disease turned up and entire herds had to be culled.
Except that the ones in this country still think that it is a good idea - they just try to keep the cows with mad cow disease from coming into this country.
(Of course now mad cow disease has been found in the USA, but they think that as long as it is just isolated cases, this is still OK to do. While we, of course, do exactly what it takes to turn isolated cases into an epidemic.)
