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 Input: 'Gun control' does not mean a ban on all self-defence
Example Output: Valid

Example Input: It's quite obvious by this and as well as the SCOTUS decision that the right to keep and bear arms is not dependent on the militia part, but the other way around.
Example Output: Valid

Example Input: No, but they might like to challenge the conclusion that states with less strict firearm laws are more often the source of guns used in crimes, in other states, than guns from states with stricter gun laws.
Example Output:
Valid
