I support laws that prohibit mentally incompetent people, convicted felons, and those with criminal records from buying or owning firearms. The fact that some laws are unenforceable 100% does not mean they have no impact. For example, traffic laws are not 100% enforceable, but they do cause most of us to drive slower, etc.
Our society has morally degraded to such an extent that some laws are necessary that were not 50 or more years ago.
Mankind is not capable of enforcing justice or without considering personal gain. That does not mean we go to anachy.
So, Yes, I do support some gun laws.
Ecclesiastes 12:13 *¶Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
14 *For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.
