Maybe, but people don't realize that the subway was open during the entire lockdown. I would be extremely skeptical that the lockdown did anything at all since it looks more like New York achieved herd immunity (or close to it) rather than it reduced any transmission. I've also not heard many people say lockdowns prevent transmission, rather they flatten the curve, but you still get the same number of people getting the virus. The flattening makes the amount at any one time much lower, so I would still be very suspicious of someone who said they were able to prevent people from getting it. Unless they are talking about a very specific group of people such as people in nursing homes.
