Killing a disarmed, caged prisoner is just killing a disarmed, caged prisoner.
This should read "Executing a person found guilty beyond a reasonable doubt by a jury of their peers and having availed themselves of the appeals process is an official execution"
I love how you, and others, try to make a convicted felon the victim. If the convicted felon didn't want to be on death row then they should not have lived their life in such a manner that they ended up on death row.
