Explain this one...

I was listening to the local news on the radio on my way to work and I heard this little piece about legislation to make it illegal to reveal the identity of someone who calls Crimestoppers. OK, that makes sense. But they also included immunity to officials who accidentally reveal a caller's identity. Well, who other that an official should know this identity. And if it is revealed, why won't they just say, "Ooops... that was an accident." Silly lawmakers.
