That is supported by their deliberations and debates.
There needed to be a standing or standby army, a 'well-regulated militia'. Such a force could be used against people but would be tempered and steered toward negotiation and litigation before force was committed because of the 2nd Amendment. The 2nd provided a check on outright tyranny then and now.
Two anecdotes:
1. The Warsaw Ghetto uprising held the Germans at bay for weeks because of the existence of a very few guns.
2. In my experience, a bum came to my door late one night and knocked loudly on my door. I answered while in my robe. The bum held his arms up high and screamed don't shoot! don't shoot! I had no gun and I asked him what he wanted. He said he wanted to sell me magazines. I said I wasn't interested and closed the door. Inside I reflected that it was good that people think other people are armed. It keeps criminals and would-be criminals in check. And my example here is a great example of why I and others should be able to own firearms without having to register them. Because otherwise criminals can find out who has and who doesn't have guns.
