In the first half of the video, Tom Cowan explains the basics of the current PCR bogus "test" and then explains what they are replacing it with. The second half of the video is Q&A on a variety of topics, not about PCR but still interesting.
Bottom line: First generation of bogus tests claimed to find a specific genetic sequence, which was never proven to come from any "virus," and then PCR was used to multiply the material to claim positive/negative. Completely, 100% bogus.
The second generation of bogus tests is going to pretend to find MULTIPLE "viruses" in anyone, and then they will claim that the person needs multiple vaccines for each of those fake pathogens (none of which were ever found in any real "virus").
Why not use bullets? Because we have more bullets than they do. This is all they have. That and they’re still fighting under the pretense that their victims are sleepy sheep who don’t now wtf is happening.
