"Resisting the stupidity and ignorance of a tin-pot chief of city police and his equally wrongheaded local political bosses just doesn't cross that threshold for me."
That is your legal and lawful choice to make. I hope for your sake you never face such a thing, too. When I joined the military, I had to think out many of the things that I would and would not do, and make my decisions as much in advance as I could, so that when and if the time ever came, I'd know what to do. One thing you might want to consider, however, is that EVERYTHING comes down to local politics. Every single gun-grabber-wanna-be mayor in the country was elected by his local people. Likewise the governors, and even the federal people. You let them get away with it at the local level, they'll do it at the state level, and above.
If we can make enough of an example of the one in NOLA, it is unlikely to come to that elsewhere, but we need to have a clear picture of what things should be like, and what it will take to make them that way. Look at Waco, for example. I've little sympathy for David Koresh, but my own church has faced similar treatment in the past. I believe that even the Baptists have had such problems, although they may have forgotten them, since it has been so long ago. The Second Amendment was intended to secure all the other rights and freedoms, most especially from our government. If we, as a people, do not stand up for our second amendment rights, we won't have anything left.
