We have similar products where I work as well, they are just expensive thermal imaging cameras. They would not be able to identify the chemical contents of a gas cloud at a distance, just that there was a cloud. The point is that in the age of digital media, its very hard to prove anything is what you say it is. Between photoshop and AI making a mess of the digital media landscape, it makes things increasingly difficult to validate, and shouting “do your own reaserch” will only add to the ambiguity as the internet is not static and can be changed by anyone at any time.
