I'm layman I don't know anything about virology but looking at the facts that epidemic afterwards pandemic emerged in the middle of the city not in some outskirts of China in remote villages but in city center of multi million town next to Institute of Virology apparently from cave bats that are 1000km away with no known intermediate host my conclusion was that scientists got infected in the Wuhan Institute of Virology spread the virus to their families and then that's how it got to the "Wet Market" which was the apparent source so called "Ground Zero" of the virus. On top of that when I heard Americans talking about how powerful and dangerous was Virus "Gain of Function" I knew it was a lab leak. So to me mainstream media is not something that can influence me a lot when I try to do my own research and thinking. Maybe I am wrong but I wait for extent scientific research and scientific consensus and result of independent American investigation which I trust more than anyone in the world because they are still number 1 country in the world looking at science, tech, medicine and innovations. Liberal and democratic country with all the flaws that come with it.
