As you can see, a comma is not necessary. The context tells you that "honors...for sins against God" simply does not fit.
Likewise, a reprieve is a "delay." What exactly is the UNQUESTIONED meaning of "reprieve....for offenses against the nation?"
It makes sense to pardon for an offense. I'm not so sure it makes sense to reprieve for an offense....especially since reprieve must have a separate meaning from pardon, so it cannot simply be assumed to be a synonymn.
An agile mind can easily avoid an impeachment EVEN when they don't hold a majority in the Congress -- cf. Bill Clinton.
GW, on the other hand, does hold a majority, and he has plausible deniability.
The first amendment does appear to give the government (any and all branches) the authority to grant a petition for a redress of grievances. The first amendment clearly gives to any and all individuals the power to petition the government for a redress of grievances, and thus it would follow that whatever branch of government is approached with that petition could grant it.
I believe that a petition for a redress of grievances would be the only available remedy to a victim of judicial tyranny and I believe it was placed in the Bill of Rights for the specific purpose of creating a check against an unlawful infringement of rights which is either ordered by another branch of government or which is denied by another branch of govenment. It is a remedy of last resort. I believe the Schindlers could have and should have used it. I also believe Bush had the right to grant it. I wonder if he would have had the will. But I'm not going to second guess Bush on this.
The heart of the ruler is in the hand of God.
