Abinadi's Death Sentence

Abinadi's death sentence doesn't make any sense to me.

 6 And after three days, having counseled with his priests, he caused that he should again be brought before him.

 7 And he said unto him: Abinadi, we have found an accusation against thee, and thou art worthy of death.

 8 For thou hast said that God himself should come down among the children of men; and now, for this cause thou shalt be put to death unless thou wilt recall all the words which thou hast spoken evil concerning me and my people (MSH 17).

First of all, it took them three days to come up with that? It just seems to me like they were really searching and stretching to contrive something to condemn him for. As for the reason for the sentence itself, the only thing I can think of is blasphemy. It seems that they extrapolated something out of the scriptures to make it look like make it look like Abinadi was blaspheming against God, as if His coming down among the people would somehow diminish His Godhood. Anyway, it is clear to me that his death sentence was totally unfounded on the grounds of the charge. I would have thought the official charge would have been his scathing remarks against the king, where he prophesied that the king would die a horrible death (see MSH 12:3).
