For the first time ever in Indiana, you can return your new baby to the proper authorities like a video rental (remember those?). America has "safe haven" laws which makes it legal for people to surrender unwanted children, as long as the baby is unharmed and given to the proper authorities or a hospital.
These climate controlled boxes are meant to allow people to drop off their kid anonymously, knowing that it will be taken care of by emergency services who will arrive within minutes of an automatic alarm.
It's a controversial issue, with some people questioning how safe it would be to leave a baby in a drop box for several minutes alone. Other people are just glad that babies who might otherwise have been left where they wouldn't get help will be able to have a safe spot to wait for a pickup by a medical professional.
