"Liberators" would be a dime a dozen if almost all had not been dumped in the ocean after the war. Unfortunately, they never contributed anything in the fight for freedom. Another idea, like the famed Pedersen device, that sounded good when someone briefed the generals, but were really worthless, even if they had been deployed.
The Liberator idea came from a fiction story called "The Moon Is Down", by John Steinbeck. The idea of arming a populace worked in the story, but was not very plausible in real life. First, just dropping the guns (the myth was that they were "kicked out of airplanes") would have made a lot of holes in roofs, something not likely to endear the populace to the Allied cause.
Second, it is hard to envision the typical French housewife, on her way to market, finding one of those guns and suddenly becoming a vengeful Joan of Arc, killing Germans right and left. Not going to happen!
The real resistance was pretty well armed, both with local weapons and with arms and explosives dropped (by parachute) by the British. They took some from the Germans, of course, but not after shooting them with Liberators.
A real resistance hero, a Polish friend, now gone, told me his group took from a dead German motorcyclist a Thompson SMG. They tried it with the 30 rounds he had in the gun, then threw it in a lake, since no more ammo could be obtained.
