People who brag about things they don't know

It just makes me sad when people use the media to talk about things they don't know about. Today I was watching TV and this man, apparently a reporter, was talking about a paternity test which had a wrong result and caused a marriage to end. I'm not saying he was wrong to bring this case up. I'm aware that some labs have some bad professionals on it and probably this was a case like that. But what really made me angry was that this man started talking about paternity tests and human genetics like if he really knew what it was all about and worse: he was saying wrong things about the methods used on this kind of tests. He ended up saying "People don't need a course to know these things!" And I asked myself: "Oh, really?" I had a whole semester at college about this matter and this man claims to know everything about it! But soon he made a big mistake. He started talking about how many genetic markers the scientists need to make a paternity test and when the host of the show asked him what were these "markers" he just said: "I don't know, I'm no expert on this matter." I only hope that the people watching it can be a bit curious and search something more about it, because he didn't.
