Slander?

[Canoris]

Ok found out today that the nurses that come around to houses directly after having a child have gone and done something really nasty.
Here we go.
They stated in there notes that my wife is an intravenous drug user.
This gets worse. They actually notified child services also.
Now i will tell you first off the bat. My wife has never and will never put a needle in her arm. NEVER has NEVER will.

Now the implications are quite bad. These notes are permanent notes on her hospital records. A red flag if you will.
Now my question is this.
Should i try sue them for Slander or Defamation of Character?
The wife is in the process of talking to the local media as i type this to see if they want to have a bite on it.

Would love some advice on this problem.

Personally, I would find the nurse, take her in the back alley and beat the crap out of him/her.... but I'm sure that wouldn't help the situation much.... just talk to the media and get a crowd, then sue them... and then go back and beat 'em. :p
