Law and legal technicalities are always a last resort. The only thing which keeps any society from crumbling is humanity's innate faith in the (by and large) good (or at least benign) intentions of their fellows. Bush has already proven (to me, anyways) that his intentions are not benign, and are fast approaching the preclusion of good.
It was not for nothing that the Founders so soberly considered, and so carefully, assiduously and deliberately included among our specifically enumerated rights that of keeping and bearing arms.
No...we have nothing to fear...so long as we remain cognizant of the bounds of human ambition, and the frailty of the spirit which constrains it.
I wonder if you are aware that your combining a statement of Presidential iniquity, with the known reason for the second amendment, and the statement about human fraility, either means nothing, or it implies a desire to accomplish the assassination of the President of the United States. If this is not what you mean to imply, you had better say so in short order.
