It's clear this is happening already before by other kids. Will whistleblowers that are being subject to abuse turn to the same tactic, certainly has a lot of shock value. The government doesn't really seem to care either way. Not something I'm recommending, but if you were left no choice? Something to think about.
Why do you want children to be killed? To what purpose? What does it mean if I'm left no choice? Who are those whistleblowers you're talking about? Please elaborate.
Edit: Do you mean if a woman's left no choice but to abort her unborn baby? Do you mean that whistleblowers against abortion shall get pregnant and have abortions as a protest against killing unborn children?
