TASK DEFINITION: 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.
PROBLEM: I believe it takes an average of nearly twenty years from the time a scumbag is sentenced to death until the time the sentence is carried out with all the various legal appeals in most states.

SOLUTION: Valid

PROBLEM: Just because the Chicago Tribune finds some "expert" in the field of arson investigation who examines paper evidence and says their may be cause for doubt does not mean that the man was innocent.

SOLUTION: Invalid

PROBLEM: There has been so much cases of people who have been executed, only to be found innocent after their death.

SOLUTION:
Valid
