I was facetious in my first comment but it is really rather sad. In many ways, America is splitting. The "ban" states are getting more restrictive. The free states are liberalizing their laws and restoring liberty to the people.
I have some thoughts for the other comments here...
For those who advocate strict adherence to the law at all times: Is there ever a time in which opposing the law is the moral thing to do? I would argue yes, absolutely. The extreme case is a genocide like the holocaust, the Soviet "liquidation" of the Kulaks, or Rwanda. If the governments demands that all good Germans turn in Jews for a trip to the ovens, do you follow the law?
There are plenty of examples of civil disobedience -- many of which landed the adherents in jail cells, mind you -- in American history. Obviously the Civil Rights movement comes to mind. I'd argue that MLK, Jr was pretty effective at lobbying from behind bars: google "Letter from a Birmingham Jail." Likewise the images of Bull Connor unleashing police dogs on peaceful marchers (who were then taken to jail...) seared into America's consciousness. Even a law which is passed by the Congress, signed by the President, and upheld by the US Supreme Court may be no law at all, morally: read about the Fugitive Slave Act and the Dredd Scott decision. If you lived in the 19th century and found a fugitive slave family on your doorstep begging for Christian charity, would you take them in, clothe them, feed them, teach them to read, and hide them, all of which would be against the law... or call the sheriff to send them back to the plantation?
Many on these forums have sworn to support and defend the Constitution of the United States. The 14th Amendment says that the fundamental, natural, specifically enumerated rights in the Bill of Rights apply to the States. Moreover, if we believe in the values of the framers of the Constitution, we believe that the core rights of religion, speech, self defense, security of one's person and papers, etc are fundamental natural rights granted by our creator to all people. Could we look on and shrug and say, "well, tyrants will be tyrants; I'm glad I don't live in that state!" if a state were to, say, start banning religion, criminalized petitioning the government for redress of grievances, or unreasonably and randomly searched people's persons and homes?
From a practical political level, we need to be careful writing off huge swaths of the country if we plan on securing the future of gun rights. 8 million live in NY, 38 million in CA, 9 million in NJ, 3.5 million in CT, 5.8 million in MD, and 6.6 million in MA. That's over 70 million Americans, or around a quarter of the country's population. I've already heard people from restrictive states being willing to compromise at the federal level; someone in CA, for example, has already lost private sales and regular mags and "assault weapons" so why not trade them away at the federal level for some sop? Our rights will not be secure if we've already lost 25%+ of the population right off the bat and the American culture of freedom, self-sufficiency, and gun rights is systematically extinguished one generation at a time.
I'm not saying that the individual in this particular case had any lofty high minded ideals. He might have been a gang banger, and it was irresponsible to leave a firearm unattended in a hotel room. I personally am not comfortable writing off the liberties of a quarter of my fellow Americans, nor am I willing to support the idea of letting states infringe drastically on a specifically enumerated natural right.
