"No more routine confinement. According to Reuters, the proposal would commit the government to ending involuntary use of apes in circuses, TV ads, and dangerous experiments."
Ummm, define involuntary? Since they more often than not seem to want to be there, as do just about any pet with memory recognition capabilities, who is supposed to define voluntary versus involuntary. More than likely, this won't actually change the roles apes play in our society, since it's easy to define them as willing participants without the ability to speak for themselves. Of course, for certain locations and certain people the opposite is true. There are activists who have spent decades claiming they can speak for the animals, and that none of them are happy being with humans. It's generally just their word, an assumption based off of their opinions and nothing more, but when they're loud enough and there's enough of them...this law may be way too generalized, as there isn't even a method to define voluntary work by animals. Start with that basic definition, then work on the laws so that they can be actually enforced.
