No, I object to an unrealistically utopian requirement deciding what is and is not an adequate means to dispose of a murderer like Tookie.
Justice is adminsitered by humans, therefore it is fallible. Just like the guy driving the car next to yours, just like the babysitter you trust your kids with, just like anything and everything else that makes modern society run.
Simply telling me that the chances are that an innocent has been or could be executed by mistake is not going to shift my opinion. Yes, I concede it can, indeed probably has happened, or will happen someday.
Would you forego your car because of innocent deaths on the road? How about getting rid of your medication because one person in a million has a fatal reaction to it? Perhaps you'd like to abandon heart surgery because there isn't a 100% success rate.
It's a fallacious standard, a dishonest argument and a complete waste of time.
Keeping it will not result in a rash of dead inncocents. Slippery slope, indeed.
