I am very inexperienced and uneducated in matters like these. Is what this post is describing a real possibility?

The canonical example from that time would be the Reichstag Fire[0].
But in an effort to avoid Godwin's wrath, it might be advisable to find examples a bit lower on <whatever scale such things are measured on> (Millihitler?). 9/11 and all the anti-terror legislation and war powers would be a more recent example.
But the point being that a contingency in government live by the adage never let a good crisis go to waste.
