An experiment which could decide against the Copenhagen interpretation of quantum mechanics has been proposed by K. Popper and, subsequently, it has been criticized by M. J. Collett and R. Loudon. Here we show that both the above-mentioned arguments are not correct because they are based on a misuse of basic quantum rules.
