It seems a lot of drug dealers are keeping large dogs such as pit bulls. To scare off the people who might steal their drugs apparently. Some are keeping snakes and other animals as well. The local officials are worried about police officers who have to go in and arrest folks with these animals. And also about children who might go around them and get hurt. And since drug dealers are not the most trustworthy sorts..there is worry that the animals might be mistreated and become even more dangerous. They are thinking of having all such animals registered and charging a special tax. Or perhaps making them illegal. That has after all worked so well with drugs..
