Caption:

This undated photo provided by the South Carolina Department of Corrections shows the state’s death chamber in Columbia, S.C., including the electric chair, right, and a firing squad chair, left

I can’t tell if it is specifically an electric chair from the tiny photo but I do know they don’t shoot you standing up. You are strapped to a chair and shot sitting down.

The article shows a pic of a lethal injection table so maybe SC isn’t releasing photos of the execution chair.
