A South Carolina deputy who during a traffic stop shot a 70-year-old man reaching for his cane broke down in tears as other officers arrived.

The York County sheriff's office on Wednesday released dashboard camera video of last month's stop. It shows Bobby Canipe (kah-NYP') of Lincolnton, N.C., getting out of his truck and reaching for a cane on a dark highway.

Deputy Terrance Knox yells "Sir" a few times and Canipe keeps moving. When he reaches in the bed and gets the cane, Knox yells "whoa" and starts shooting. Knox then almost as quickly seems to realize Canipe had a cane, then cursed and rushed to help.

Sheriff Bruce Bryant says after watching the video he still thinks the officer did the right thing.

The shooting is being investigated.
