Given the task definition, example input & output, solve the new input case.
We would like you to assess the QUALITY of each of the following argument (discussing Gun Control) 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 gun control. An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of gun control.
Example: If gun bans worked there would be no gun deaths in the countries that have banned guns.
Output: Valid
It is an argument that claims that gun bans will not work.

New input case for you: Previous 9th Circuit rulings, stating that the Second Amendment was purely a tool of government to maintain the National Guard rather than guaranteeing the right of the individual to be armed, were never taken up by the SCOTUS.
Output:
Valid
