So you don't support a death penalty as well.
Okay, what if your family member was murdered and the right person was caught, would you still want that person alive? 
If I were you, I want that person dead.
As for innocent people to be executed, it happened to a lot of innocent black men in the past like 30s to 70s as I am aware of. But today it ain't happening because we have a high technology to prove it.
