As a police officer in his official duty he has no dammmmm
business talking to people about his religion, much less send them a letter from their personal information he obtained through the arm of the law!
If you want to go around telling people about your religion and feel commanded to do so, then don't get a job as a police officer. The law protects all of us, whether we are Christian, Jew , Buddhist or Druids, or atheists. If I was preached to by a police officer about a bumper sticker and my religion I would wonder if I was dreaming and was living in the land of the Taliban!
As for all the silly posts about" You don't know if that really happened" we are assuming FOR THE SAKE OF ARGUMENT on the issue..that this incident did happen.
You seem to still be a bit of a hippie.
In any event, the letter was an abuse of power.
But, not mentioning the love of Christ in passing.
You don't seem to understand American authorities did much more than this in the early history of our country, even giving tax money to convert the Indians.....paying Christian missionaries and giving funds to build churches.
Church was held in our government buildings, and often govt. leaders attended.
In the army, soldiers were often punished for saying the Lord's name in vain and were strongly encouraged, sometimes required in the Civil War by Lincoln himself to observe the Sabbath.
oh, and yes, all these things happened well after the First Amendment and were even upheld by the courts.
Heck, the NY or Mass Supreme Court (can't remember which one) said the Bible should be read "as divine revelation" in the public schools.
It was not until the 20th century that our weird view of a separation of church and state came into being.
