An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of death penalty.
PROBLEM: I have gotten about a dozen people to take my "try it before you shoot off your mouth" challenge, and every single one of them changed their tune by the end of their little adventure.

SOLUTION: Invalid

PROBLEM: Are we talking about what crimes are justifiably punished by death, or merely the validity of capital punishment as a Biblical measure?

SOLUTION: Valid
