We would like you to assess the QUALITY of each of the following argument (discussing Death Penalty) and determine if the argument is Valid or Invalid. A valid argument is clearly interpretable and either expresses an argument, or a premise or a conclusion that can be used in an argument for the topic of death penalty. An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of death penalty.

What I mean is, that NO punishment would be legitimate.
Invalid

However, one advantage with the Death Penalty is you can use it as leverage in plea bargains.
Valid

In any case, while I believe some criminals should just be carried into the street and shot, I don't think the death penalty is worth it in today's society.
