Who is to blame for this shooting?

According to ABC news a woman was shot by a border patrol agent in California because she hit the agent with her car and did not even border to stop the car so the agent shot at the car so as to stop the moving car unfortunately she died.

                                                        her windscreen

BUT the woman's family thinks the officer over reacted.Anyway, the FBI is investigating the case.

Seriously? how can they say he over reacted?
I am not saying she deserved to die but i guess the border patrol agent just did what came to mind since she didnt stop.
