TASK DEFINITION: We would like you to classify each of the following sets of argument pairs (discussing Gun Control)  into either SIMILAR or NOT SIMILAR. A pair of arguments is considered SIMILAR if the arguments are about the same FACET (making the same argument), and is considered NOT SIMILAR if they do not have the same FACET. A FACET is a low level issue that often reoccurs in many arguments in support of the author's stance or in attacking the other author's position.
PROBLEM: Sent1: That pretty much boiled down to laws against felons having weapons, laws against the mentally defective having weapons, and laws against carrying weapons in sensitive places.
 Sent2: And where laws were passed, the gun lobby has had success in watering those laws down.

SOLUTION: Not similar

PROBLEM: Sent1: now imagine if no criminals could get hold of a gun, you wouldn't need a protection, as no criminals have guns.
 Sent2: Also if both points are true, would you sacrifice you right to protect your rights with guns (rather than politically) for a crime rate low enough where you don't feel you need a gun for protection?

SOLUTION: Similar

PROBLEM: Sent1: FACT: Because it is already illegal for convicted felons to own guns, the Fifth Amendment protects felons from being forced to incriminate themselves by registering their guns.
 Sent2: If guns are banned, the only people that will be affected will be the people that buy guns for protection from criminals, who get their guns illegally anyway.

SOLUTION:
Not similar
