Only 1 in 20 gun owners are very proficient with their firearms and out of those less than 1% would use them to try to protect their families or selves from uniformed force. The govt. knows that.
Just like in Germany and Russia, when the police raided peoples homes and hauled them away, the neighbors shrunk in fear and said,"at least it wasn't us". And they kept saying that until they had all been dealt the same fate.
Bear in mind those stats, if accurate, are those who have already put thought into the matter. Future events may cause many to re-evaluate their stance on such matters.
