Ask that question to Jefferson Davis, he is the one to make that decision.
Pinning the blame for it on someone is not answering the question as to probability of resistance.
The probability of resistance was hovering around 100% and everyone involved in the affair knew fully well that resistance would be forthcoming, so the orders simply default to using force.
Lincoln knew there would be resistance. Gustav Fox knew there would be resistance. Anderson knew there would be resistance. There wasn't a single man on either side who believed there wouldn't be any resistance.
