Increments, dribs and drabs, death of a thousand cuts--it will keep getting worse as long as people trade liberty for the illusion of security. Trouble is, we are preaching to the choir here. Gun owners are more concerned than most about BOR issues. Most people aren't concerned about wiretaps or kicking in doors, because they see themselves as law-abiding citizens who will never be on the receiving end of such tactics. In fact, they vote for politicians who promise to "get tough on crime". I know I have been guilty of thinking "Kick the door in and get those scum off the streets". The trouble is, at some point in time, something I consider a right may be classified as a crime. One has only to look at Great Britain to see how quickly a proud and independent people can surrender their rights to an over-protective welfare state. They are now setting up portable metal detectors to spot-check pedestrians for knives, even tiny little folders. Don't even think about owning a gun unless you are part of the landed gentry and hunt pheasants or red deer. They all had to turn in their registered pistols a few years back. Never happen here? I am beginning to think 1984 came in 2006.
What course of action-- get politically involved with efforts to elect politicians who know the whole Bill of Rights, not jut the Second Amendment. And have a stockpile of at least 1000 rounds for your shtf rifle, because security begins at home.
