I said in my comment that I think that it might be that lock downs worked in certain situations, but not all. From your comment, it sounds like there is no amount of evidence that will convince you that lock downs are more nuanced than the statement that they are 100% effective in all cases.

Remember, they weren't really full lock downs, they were these partial kind of lock downs. Even in the US, some places did curfews, some did not. At the very least, you have to admit that there have been some measures under the lock down umbrella that were not as effective as others. If you can't even examine your faith in your statement, you are right that there is no point in discussing this subject further.
