In a week of tragedies that also includes the sniper shooting in Dallas and the shooting of Alton Sterling, Reynolds' video stands out as a defining testament of how we live now. He said the ongoing investigation was a top priority and that he would decide whether to give the case to a grand jury after investigators presented their findings to his office.

It's hard to predict to what extent the Reynolds video, for all the attention it's gotten, will impact the political scene; to many sets of ears, her calling the man who's shot her boyfriend "sir" will sound like simple respect, the way things should be.

St. Anthony Police Officer Jeronimo Yanez shot Castile several times during a traffic stop Wednesday night.
The bureau says Yanez approached the driver's side of the vehicle and Kauser approached from the passenger side before Yanez shot Castile multiple times.
Police say the group made their way to a nearby commercial street where they broke the storefront window of one business as well as windows of an unattended police squad auto. The races of the officers who were shot have not been released. Police, including state troopers, were in tactical gear, but there are no reports of any violence.
Yanez's attorney Thomas Kelly declined to comment on Friday. She recalled cautioning him to always comply with police, but she said she never thought she would lose him.
"This has to cease".
