The more important question is what the authorized method should be?
If you don't like the way it is being done, what do you propose?
Should they(the clinic or the mother) be required to provide a shoe box sized or match box sized coffin, conduct a religious service, and bury the remains in a graveyard?
Would you allow for cremation(incineration aka thermal oxidation) of the remains and require the mother to accept the thimble sized jar of ashes?
Lets be honest. The modern anti-abortion methodology is to raise the cost and shame the woman.
Put the remains in a clean container and give them to mom for burial.
