@electricmeatorchestra presumably, if someone were using a digital menstrual calendar and realized that (1) they were pregnant, (2) they wished to terminate said pregnancy, and (3) they lived in a state where this was not allowed (as, for example, under a law where this would always be prosecuted as fetal homicide), this data could and WOULD be pulled for the sake of their prosecution. the data being unreliable, on the other hand, would serve to the defendant's defense through the impeachment/unreliability of the data itself. for lack of a more eloquent way of putting it, if you have to prove things beyond a reasonable doubt, a history of people fucking with the data DEFINITELY casts some doubt on this lynchpin evidence, does it not?
