没有根据的情况下最好不要瞎猜。仔细看报道,后面那人就想杀人。小留只是不幸撞到枪口上了。http://www.azcentral.com/story/news/local/tempe/breaking/2016/01/16/woman-shoots-driver-after-collision-6-hurt-tempe-police-say/78907610/:
“The woman arrested in the fatal road-rage shooting of a 19-year-old Arizona State University student had said she wanted to be shot by police and had left a note behind saying she planned to commit a violent act, according to records in the case.
Holly Davis, 32, was arrested on suspicion of first-degree murder and a host of other crimes following the Saturday fender-bender in Tempe that escalated into a homicide.
Davis crashed into a vehicle, then got out of her car and fired at the car she had hit, police said, killing the driver, Yue Jiang, an exchange student from China.”
