The first thing most people do when they get a brand new digital camera is turn off the stupid sounds it makes when it takes pics. If you've ever been to a wedding, it sounds absolutely awful when peoples' cameras are sending off chimes and fake shutter sounds left and right during a quiet ceremony. Mobile-phone cameras are supposed to be transitioning towards being more like a dedicated point-and-shoot. This would just make them annoying.
I'd like to know how the bill would require manufacturers to make it impossible for a user to put a small piece of tape over the speaker to silence the sound (or their thumb)? Maybe all camera users will be required to remove their thumbs!
The real problem to is that with this law in place people will feel more comfortable because they know that weirdo's phone isn't makeing camera sounds. When in actuality its been modified(to be silent) and said weirdo is taking all kinds of pictures. Once again government regulation fails and only makes things worse.
