If I were a robber or burglar, I would choose the home with no gun to break into.

If I were a government and I knew my target had weapons, I might think twice before messing with them. I might still do it but I would think twice before doing it. If I were on the fence regarding the decision, I might decide against it because of the weapons.

As long as I have weapons, I could ban together with others and cause a lot of chaos (sound like the Middle East). Having that knowledge a government decision might be swayed.

If it was a strong decison, then I have no doubts the government would proceed and the guns will make little difference. Just an annoyance to them.

So many guns, so little time!
