it only endorsed keeping a handgun for home defense. Interestingly enough the ruling happen to fall right in line with what the overwhelming majority of americans believe.
If there was ever a justification for confiscation of weapons, this group and others like it SHOULD NOT BE at the top of the list. Tell me, how many crimes do "militia" members commit every year? How much of a real societal problem do they cause day to day? Very little. Yes, they are whackos, and some of them are dangerous, but the matter of fact is they are a very very very small group of people. If anyone should be on the top of the list, it should be anyone who lives in innercity neighborhoods. Atleast that would make a sizable dent in firearm related crime.
Also, look at any unintended consequences of focusing on these nutjobs. you essentially play into their hands. Now their paranoia has a basis in reality. You could potentially make them even more violent and get others to join their cause.
I find the best thing do with these people is essentially ignore them. When they committ a crime you arrest and prosecute- but don't turn it into an ideological/political battle. When my father went to work one day and found a swastiza spray painted on the side of his office, he didn't call the police, he didn't call the Anti-defemation league, he didn't call the media and "take a stand against hate"- he went down to the hardware store and bought spray paint remover. Their hasn't been another incident since (20 years). To counter that, the same situation happened at my HS about 10 years ago and a whole big-to-do was done- meetings, "press conferances", etc....All it did was cause more vandalism to occur (IIRC 4 more incidents occured in the following 3 weeks).
The moral of the story is- sometimes it is better not to bring attention to things. Treat these "militias" as your "crazy grandpa". Let them speak and then say "okay thats great, now its time for you guys to go back to the hole you came out of".
