Changes to the state driver’s manual are in effect today with new information on what drivers and law enforcement should expect during a traffic stop–especially when a driver has a firearm. The changes were prompted by a push from Valerie Castile–whose son Philando was shot and killed by a Falcon Heights police officer on this day in 2016. At a press conference this afternoon, Valerie Castile called it “a bittersweet day, it’s been four years now and it seems like yesterday, we’re talking about 1,461 days that I have not seen my son, have not touched my son, have not kissed my son.” Castile called the changes to the manual “very important. That bit of information can save lots of lives because you don’t know what you’re going to get when the police walk up to your car.” The changes in the manual advise motorists with firearms to keep their hands on the steering wheel as the officer approaches, let the officer know they have a firearm and tell the officer the firearm’s location. And in return, officers are advised to identify themselves as law enforcement and inform the individual of the reason for the stop and explain the circumstances for issuance of a citation or warning.
