Innocent animals don't deserve to be tested upon whereas prisoners who are already in line for certain consequences seem a more viable choice for testing.
Criminals do not have the same rights as the citizens do. However, I prefer the appliance of choice.
Well, with medicines or similar things, otherwise test on animals
Not unless they volunteer and reasonable precautions are taken i.e. you test cell cultures first. If your American this definitely breaches cruel and unusual punishment and is way beyond the acceptable bounds in western European courts.
No. All humans, even prisoners (except for the particularly evil ones like child abusers, murderers, etc.), have basic rights.
Even the most professional criminal is HUMAN,and by the meaning of being a human its totally against the right of humanity
When you consider the amount of people who are falsely convicted, this is a terrible idea because innocent people would be the victims of this testing.
Obviously not, this would simply make the problem we currently have worse. It would give many corporations incentive to twist the system so that more people are imprisoned.
If you value human life over animal life, this is a one and done situation.
