What I've read is that they tested something like 15k PCR tests that supposedly tested positive and could not find anything on them when doing a more comprehensive test.
I do remember the swine flu. Me and my boyfriend at the time both got really sick but there's no denying that all those supposedly positive PCRs were all false.
It's not illegal to do undercover journalism. In fact, this is something actual journalists used to do. These people aren't journalists, they're propagandists.
