You dont need specialized teams of people to testify that the photo on the right[0] is fabricated. Any police officer on duty could do that. You dont need people to say "the bridge is sound" just that the rumours are false.
Its like certain societies enjoy the rigidity they are in.
But i guess in a country where a "retweet" of the wrong opinion can get you in legal trouble it just easier to say that fabricating and propagating ai slop is also ilegal

Network Rail deal with dozens of reports of earthworks failures, landslips, vehicle strikes, and other problems affecting bridges and viaducts every day. They have well-tested procedures in place to investigate them. In some locations, and at some times of day, those procedures involve on-call staff.
Sure, "just follow the process" is a lot less exciting than coming up with an ad-hoc response - but when you're dealing with safety-critical infrastructure at scale, it makes a lot more sense than cowboying it and hoping for the best.
