I am trying to remember for what reason I had to show my blood card at a DC in the early 90's. The only reason it sticks out to me is I remember the comment being made from the podium that many of the cards of JWs were not in fact signed, and therefore would not offer "protection." The fact that some JWs did not have their card signed is of interest to me too (after all, why bother having it if you don't sign it?), but I'll start a new post on that
Anyone remember this, and what specifically was given after your blood card was checked?
