As far as I know, animals have neither privacy nor civil liberty. It has nothing to do with ACLU's business. So the solution to deal with BSE is very simple. Track 'em. Fingerprint, DNA sample, and hot-iron-mark all animals. With this system established, all contacts can be traced and destroyed if necessary once a sick animal is found. This is very good for economy. Boost spending and IT industry. By the way, the sick animal in Washington came from Canada. There would be no dispute about it if there were a full animal database online.
