In case you've missed it, we are a nation of laws and the legislative and judicial systems are the constitutional responsibility given to the government by the people. Who else are you going to empower with the death penalty?
That's an ideal view of our government. In a perfect world I would trust them to carry it out, but let's be realistic. The government has dropped the ball across the board time and time and time again.
Oh and in case you missed it, the people of the country give nothing to the government in the Constitution. The Constitution doesn't grant the government any powers...it restricts what the government can do. That's a big distinction. You really should study it sometime.
And you didn't answer my question. Why do you trust the government with the death penalty? I'm assuming you don't trust them with health care, regulating the economy, etc.? So what gives?
If it's because you like the death penalty as a concept--once again I agree in a perfect world. BUT this government has a really bad track record, including the death penalty.
Roughly 4% of people executed are found to be innocent. Like you said how could you tell a family coping with the death of a loved one that the murderer is still free...how could you tell the family of a wrongfully executed person "sorry"? It goes both ways.
