Lucy Letby was convicted last year of murdering 7 babies and attempting to murder 7 more while working the the nic u. She's serving life in prison, but if there's a medical "professional" that maybe deserves a classic public hanging, she could be near the top of that list. That's just one that comes to mind, but if a doctor like Nazi Josef Mengele were to be discovered, I'd also say they should get a hanging.
