“How about you explain how a hospital gets blown up and only kills 3 people. You can use OKC for comparison (similar sized building being blown up).”
The majority of those killed at the Murrah Building died when the building collapsed. From what I’ve seen, the hospital — or what has been described as a hospital — came nowhere near collapsing.
True, it did partially collapse, but I still struggle with a death count so low in an active hospital - it’s not like you can evacuate everyone in 30 seconds if you know it’s incoming (if).
