I don't think you need much evidence to believe that lockdowns are temporarily effective. But I'd be curious to see evidence on whether they are effective at reducing overall infections over a longer period. Because it seems like they just delay (for only a matter of weeks) what is going to happen anyway. Most of the United States really had two significant waves. NY and other early hotspots never had the summer peak. The summer peak states never had a huge outbreak in spring because they locked down two months. The states that managed to not have several outbreaks until fall (California and the Planes states) all got hit much worse. It all seemed to even out.
