Nobody died, that's what happened. I'm simply answering your hypothetical if the Senators were actually killed. If the Sentors and/or the VP were taken as hostages, or worse killed, it would mean national guard was either complicit or incompetent. However, as we know, the Secret Service sadly had to act with deadly force and managed to secure the legislature.
