This is a terrible line of thinking, SARS-CoV-2 has some interesting properties, but none that would indicate deliberate weaponization. Useful bioweapons also usually are a little bit more surgical, China got hit pretty bad at the start of the pandemic.
I'm saying that you can not base probable cause on such flimsy evidence. Especially if it is self-fullfilling.
And also, yes, swatting is a really big issue. Maybe the police should not show up in military gear and itchy trigger fingers to every unsubstantiated anonymously called in. Not saying that they shouldn't do nothing.
So if nation develops biological weapons by creating viruses in a lab, we just ignore it?
