His job was to make sure that abortions were performed, even to the extent of using physical force to ensure that they would be performed.
Or are you saying that the body guard had more complicity than the receptionist who scheduled the procedure, the salesman who sold the tools of the trade, or the bookkeeper who helped the business stay open?
It is not an issue of complicity. It is an issue of immediacy.
All you are trying to do is to condone the act of murder while simultaneously condemning the act of murder.
Again you describe the act of using deadly force to prevent a murder with murder itself. You have not yet offered any explanation why using deadly force with the intent of saving another person's life is murder.
Instead you engage in an endless, psittacistic begging of the question which is under debate.
No, his job was to make sure that the doctor was not hurt.
The receptionist's job was to make sure that abortions were performed, as is the medical supplies sales people, as is the attorneys and accountants who helped keep the business going.
You simply need to justify a murderer's actions to your own satisfaction.
I'm still waiting for you to prove that he saved anyone's life.
