Why isn't there a movement to pass an amendment to the Constitution guaranteeing the right to privacy? Are there any legitimate concerns raised by making it explicit? Every up has a down (e.g., free speech means I must tolerate hate speech I find offensive) so I'm curious what the downside of such an amendment would be.

I was home sick today and I had the Alito confirmation hearing on the tube. Drifting in and out of sleep while listening to senators pontificate led to weird thoughts and it occurred to me that we spend a lot of time and energy trying to pin down a nominee on an issue that we should just make a declared right.
