Live ones do.
That is the real issue.
One when I referenced a Dragnet episode about a little infant girl found in a garbage can outside I went to look it up and was dismayed and surprised to find pages of Google search results of incidents in various cities and towns with babies in dumpsters or trash bags or trash cans, one after another. Not a rare thing.
Even with the firehouse and police station agreement to not ask any questions if a baby is left there.
