How much investigation? How much protection?

First, unless the Congress enacts a law giving the unborn the protections of legal status, states can have no power to regulate abortion as a medical procedure. If they were to enact protection, then the question becomes "when?" See https://datayze.com/miscarriage-chart

Here is the data by likelihood of miscarriage - meaning that at this point, pregnancies must be registered and all deaths and terminations (including post-stillbirth) investigated with the mother liable for ordering manslaughter. Note that if one kind of contract killing is exempt, contract killing cannot be a crime.

3 weeks gestation (around 5 after last period), 30%

4 weeks, 25%

5 weeks, 19%

6 weeks, 5 days, 10%

8 weeks, 5.2%

10 weeks, 2.5%

14 weeks, 1% - meaning that 1 out of every 11 losses is miscarriage, 10 are abortion.

16 weeks, 0.5%

19 weeks, 0.1%

20 weeks, 0%

Then the question is survivability after birth. See https://www.healthline.com/health/baby/premature-baby-survival-rate#28-weeks

23 weeks and before, more than half die. Those that don't will be damaged for life.

24 weeks, 60% survive. Of those that do, 40% have permanent injury. Survival requires NICU support. Note that morally, such support is considered extraordinary and therefore morally optional.

26 weeks, 68% (between 60 and 70), 20% have health problems for life.

28 weeks, between 80% and 90% survive and with great care between 94% and 98% with 10% having lingering health problems

30 to 32 weeks, 99% survive. Third trimester starts here. These children are late preterm. After 33% weeks, 100% survive. The law considers all such children as people.

Where do I stand? I want no parent grieving a miscarriage to be interviewed by any coroner, detective or over-zealous pro-life prosecutor who graduated from Ave Maria or Liberty University Law School looking for bona fides for a congressional campaign. That is 20 weeks. After 20 weeks, only induced labor and fetal hospice would be allowed, no slicing and dicing.

Regardless, no child who is sure to be stillborn has a right to life at the expense of his or her mother's health and should be taken as soon as possible for that reason.

Of course, if one of the 5 Alito justices changes their mind, any kind of abortion regulation must come with full support of Build Back Better as a pro-life issue, except that the child tax credit must be high enough so that child support is never required and the minimum wage must be high enough so that no one will live only on their child credits. Work must pay. 

Daycare must also be free to employees, although Congress should pass tax credits for employers to offset these costs - at least partially.

Anyone with under 10th grade literacy in English should have only one job - gaining literacy at this level - payable at the minimum wage with child credits. That includes ESL students, who must be eligible regardless of immigration status.

To be considered pro-life, supporting these issues must be considered mandatory by the Catholic bishops. See the other article from today about the current pro-life Putinist agenda.
