Like companies outlawing growing your own garlic and onions because someone somewhere found that you can make a moderately effective mace with those ingredients

Like companies outlawing growing your own garlic and onions because someone somewhere found that you can make a moderately effective mace with those ingredients, or because they can be abused (war on drugs), or because terrorists. You might raise issue with the idea of a corporation outlawing something. I say look at the way the justice system currently works and tell me they couldnt buy the result they wanted.
