However (in fairness I'll disclose that I'm a U.S. citizen) the length of time to enforce the executon is due to the numerous appeals that have to be satisfied by various courts.
Tell me about the kids that supposedly are executed...
Or does it come down to your definition of a "kid"
The problem with stating "the death penalty doesn't deter crime" is that it's statistically impossible to interview or otherise identify people that didn't commit a crime by way of knowing, if caught, the could be executed...
And... the courts and laws themselves have defined 'intelligence' (actually it's the ability to know right from wrong and to assist in providng ones defense) therefore, by reasoning that ones intelligence shouldn't be a defining factor would automatically make every defense one of "ignorance of the law", no? In which case, no one would be punished for anything... ("Sorry, your Honor, I didn't know that's what the law says"... "That's Ok sonny... just run right along now, just be careful of the next time though")
