I don't see anything in those verses you quoted, one way or another, about mourning. I strongly advise against adding words to the scripture.
The Romans were not blamed for the crucifixion:
"For ye, brethren, became followers of the churches of God which in Judaea are in Christ Jesus: for ye also have suffered like things of your own countrymen, even as they have of the Jews: Who both killed the Lord Jesus, and their own prophets, and have persecuted us; and they please not God, and are contrary to all men:" (1 Th 2:14-15 KJV)
>>>John is providing evidence that Jesus fulfilled the Messianic prophecy of being pierced so that ye might believe.<<<
And I believe.

I forgot this point and question in my previous post. This is Zechariah 12:10:
"And I will pour upon the house of David, and upon the inhabitants of Jerusalem, the spirit of grace and of supplications: and they shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for his only son, and shall be in bitterness for him, as one that is in bitterness for his firstborn." (Zec 12:10 KJV)
If to a "literalist" the phrase "all the families that remain" means "every person in every family," and "a thousand years" means exactly 1000 years, then who are they who pierced him?
