The fatal police shooting of Olango, who drew something from his pocket and extended his hands in a "shooting stance" happened about a minute after officers in a San Diego suburb arrived at the scene where a mentally unstable man was reportedly walking in traffic, a police spokesman said Wednesday.

In this Sept. 15, 2016 photo, the Rev. Moses Colbert poses for a photo at his church in Gastonia, N.C. As Americans prepare to cast ballots for the next president, the voting process has never been more convoluted. A federal appeals court over the summer struck down several parts of a North Carolina law that not only required voters to show photo ID but also reduced early voting and eliminated same-day registration during the early voting period. Colbert, a black pastor from Kings Mountain, N.C., was among those who challenged the law after finding himself unable to vote in 2014. (AP Photo/Chuck Burton)
