My understanding of SB8 is that it doesn't allow prosecution, but rather allows private citizens to sue anyone involved in the abortion for $10k each.
So any citizen of Texas could sue the driver, the Dr., the Nurse, the receptionist, etc for $10k if an abortion was performed that ran afoul of the law. That's how they sidestepped Roe v. Wade, by not having the .gov enforce it.
I admit though, I haven't read the bill, only the various pundits opinions. I will reserve my opinion until I get around to reading the actual bill.
