Homicide Playing Cards for Florida Prisioners?  

Remember the "most wanted terrorists" card decks that were issued to soldiers in the Middle East? Well, Florida has issued like 90,000 decks of cards featuring cold case homicides that they need help closing. They've issued these decks to prisioners. Hoping, I guess, that if the prisioner has any information about the crime, they will call the number at the bottom of the card. I have seen one of the cards online: fdle.state.fl.us/OSI/Unsolved/cards/Cards.html
This site has both decks but being as I am not from Florida and I have no knowledge of ANY homicides anywhere, I didn't see the point of my looking any further than the first card.
My question is: Is this effective police work or just cheap thrills for convicts? The cards are full color photos of the victims with information about the crime or suspected crime. For the crimes that involve children, no photos are shown, just photos of their belongings or clothes, etc.. In theory, if I were the relative of a victim, I would not like to think of convicts sitting around playing poker or rummy with pictures of my loved one and details of our tragedy! Not to mention, you just know these cards are going to turn up on ebay! Yet,by the same token, I would want anything and everything to be done for the sake of justice. If this method is effective, wonderful. Either way, it seems kinda morbid to me. What do you think?
