Pippa Middleton was in the front passenger seat of an Audi Convertible in Paris on Saturday when the driver of the vehicle pointed a semi-automatic handgun at the paparazzi.
A witness filed a complaint with the Paris Police, and a judicial source told Us Magazine:
"If the evidence points to [Pippa Middleton's] involvement, she will be prosecuted. Anybody involved in the illegal use of a handgun in public is liable to arrest and interrogation."
In France, heightened, anti-terrorist security measures forbid anyone to use a gun to "warn people off".
Must have been really scary for onlookers!
