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.

For decades we have proved drug cases by having a scientist who tests the drug submit an affidavit which says ���its cocaine��� or ���its marijuana������without having to call the scientist to testify about his findings.
Invalid

Those are all the government, if it has gotten as far as the people, and the government (the president, the congress, the supreme court) has decided on gun control, who's going to arrest them for it?
Valid

We therefore hold that the Due Process Clause of the Fourteenth Amendment incorporates the Second Amend-ment right recognized in Heller.

Valid
