I've been to Sweden twice in my life, and I've hit these border checks three times (I believe they were the first country to bring this stuff in—about 5 other countries have done so since) and also seen the same happen on one occasion coming from Copenhagen (by bus); someone being "caught". Nothing about that indicates to me that this is warranted, effective, or not purely motivated by paranoia. Who were those that were "caught" in your encounters? Did you get their names?
