TASK DEFINITION: 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.
PROBLEM: We exhibit to mankind the remarkable spectacle of a people attacked by unprovoked enemies, without any imputation or even suspicion of offence.

SOLUTION: Valid

PROBLEM: There is no reason law-abiding citizens need to defend themselves as they are untrained, do not have full knowledge of the law and eventually cause more harm than good by owning such weapons.

SOLUTION: Valid

PROBLEM: Or maybe that implementing gun control is too cost prohibitive to be effective and thus an exercise in futility and serves no logical purpose?

SOLUTION:
Valid
