It could easily be a natural virus that was collected, but leaked from a the lab that studied it. To me, it makes sense to look at biohazard lab safety procedures if there was even a chance the lab was a factor in its spread. It’s possible to make mistakes while following best practices, or that those practices themselves need improved. It’s sad that it’s become a blame game of who caused the pandemic, when what we really need is an impartial account to prevent the next pandemic.
