1942 Battle of L.A is extremely overhyped. It wasn’t anything more than a bunch o jittery AA batteries shooting at nothing.
My grandfather was an air raid warden at the time and the only thing remarkable was that a piece of shrapnel fell close enough to where he could pick it.
I certainly agree with you that the cause isn’t in any doubt, I’m just confused why the federal government was so reluctant to admit any responsibility. It apparently took them until 1983 to admit the truth.
