Paparazzi: How Far is Too Far?

I think the paparazzi are just really ridiculous.  People deserve to have their privacy even if they are celebrities.  I personally don't care if i see a picture of a celebrity outside of their work place or not.  But photographing celebrities' children is just insane.  Paparazzi just don't know when to back off.  They need to find a different proffession because things are getting ridiculous.
