I said earlier they didn't want to have a big opposition because of how it would look if they did show significant force and use it. I have no idea how this is different.By Sund's account, he wanted National Guard once the rally limit expanded but the heads of security for both houses (both also resigned) said they did not want National Guard there because it would look bad. Chief of the relevant National Guard has said they repeatedly offered their support and were declined by Sund.
Imagine if you were sending an infantry to battle and you said "we're going to try to win this war. We're sending 1 guy in for every 20 of theirs, but believe us, we're really trying here".
