Scientists speak out on being silenced when raising concerns about coronavirus lab leak theory

This is very sad. We are in the middle of an endemic disease that has killed millions. It seems that there was a lot of scientific evidence that the covid virus escaped from a lab. Scientists that suspected the virus was from the lab were silenced. A counter explanation for the origin was presented and efforts to present any other theory was silenced. A Powerful scientists had a letter signed by other scientists and published. If the left is going to go after people for supposedly presenting false information about covid why aren’t the left going after scientists and government officials suppressing the truth or at least suppressing plausible alternate theories of COVID’s origin.
