Keep in mind a bill is only the first step. Implementing a bill will require guidelines to be written by bureaucrats. Generally this is where some form of an informed consent requirements would be established. To expedite the bill, I would think the informed consent already used by drug companies would be a requirement. Unless the Feds already have a consent form on file using the current standards established by companies would expedite implementation, take the government out of the process and of course limit Federal culpability.
