Part of this book is the claim by Dr. Nikolai Petrovsky [1], a nonpartisan professor, that Covid-19 cannot infect bat cells. Petrovsky's original papers on the lab leak hypothesis was rejected by the Big Journals, and censored by BigTech [2] after the issue of a lab leak became politicized [3]. The question of being able to infect, or showing low selectivity is a key one. If Professor's Petrovsky claim that Covid-19 cannot infect bat cells, and is ideally optimized to infect humans only, it raises serious questions.
Professor Petrovsky also postulated a third scenario, that this was a coronavirus accidently cultured in lab experiments, not a research target, making a lab escape situation fundamentally different.
politicizing the Covid origin issue was one of the most successful propaganda operations of our times which allowed to completely derail any real research of the issue. Not surprisingly given how US and China interests are aligned on it - kind of an example of successful cooperation :/.
