The government doesn't care about your personally owned firearms. Besides, if you live (or have lived) in a state where private sales can be accomplished without paperwork, who really cares?
Uh, you think the government can't find access that search engine? Or that anything you do on a smart phone, tablet or PC can't be tracked?
Let's face it: we are so far beyond anything Orwell could have imagined that it just doesn't matter anymore. (And for some reason, I keep picturing scenes from that classic 70s sci-fi movie with the beautiful Jenny Agutter Logan's Run ... )
