A lot of what you mentioned was written by Peter Daszak who is one of the main suspects in terms of lab involvement in the origins. The closest wild strain to covid was found in Laos and there is no wildlife trade to Wuhan but Daszak's organisation seems to have been collecting samples there and shipping them to the Wuhan lab. And then when people say "what samples, lets see" you get stonewalling. Before having too much of a go at the Chinese we should subpoena and get the records from that lot (based in NY).
