Signing on to bad treaties is bad. Treaties can both restrict what you can do and compel you to do things that you don't want to.

For example: "Compelled Technical Assistance: The draft requires countries to adopt laws enabling authorities to compel anyone with knowledge of a particular computer system to provide *necessary information* to facilitate access."

The US would have to have laws that would force you to provide login information to systems if the government wanted access to it. This would run contrary to the 5th amendment.
