What is the papparazzi?
user
Papparazzi is an Italian word that literally means "buzzards".  It has come to mean people who take pictures of celebrities without their permission, which is widely considered to be morally wrong.  This is the origin of the modern meaning of the word.  The reason I’m explaining this to you is that I want you to understand why people are called “papparazzi”.

Have they ever endangered a celebrity's life?
user
I don't know, it’s not my area of expertise.  Papparazzi are often regarded as interfering with celebrities’ rights to privacy, and this can be bad for them.  They can be liable for assault in cases where they’ve deliberately put celebrities at risk, and also they can be subject to legal cases for trespass.
assistant
Have there been any instances where papparazzi chasing someone has caused a traffic death.
user
I don’t know of any, and again it’s not my area of expertise.  I do know that there was an incident in Paris, France in 2006, where a photographer went onto a moving vehicle, then fell off and suffered a head injury and died a few days later.  I think that counts as a traffic death.  If you have more details, I’d be happy to help.

What about the death of Lady Diana?
user
That would be the death of Princess Diana.  The driver of the car she was in was intoxicated.  We should remember that many countries, including the UK, are still grappling with issues around drinking and driving, and the dangers of under-reporting accidents.  I don’t think that anyone blames the paparazzi for this, but I do know that Prince William has had at least one complaint against the tabloid newspaper for publishing his mother’s death.  He has also campaigned against media intrusion into private lives.

I’m not sure what you mean by that.  Was she killed by a traffic accident?  I’m not aware of that, but if you have more details I’d be happy to look into it.
