It looks like good old investigative journalism, and not conducted by the usual heavyweights.
So 'armchair' investigators apparently beat thousands of 'professional' Russian FSB/DoD investigators.
These spies used GRU HQ address on their undercover passports. They registered over 300 sequential vehicles all to spies. They used their real names! This wasn't a "Bellingcat isn't credible" situation but a "GRU failed at basic spycraft" situation.
That's the point of free speech and free assembly. People are allowed to be wrong.
I'd rather have too many people asking questions and investigating rather than too few.
This brings their investigations much closer to simple join-the-dots exercises.
Remember there are always at least two sides to every story and to question everything because everyone has an agenda.
On emailing classmates, that's probably trivial. Lots of school classes have Facebook pages or WhatsApp groups, or mail groups or such. These can be trivially easy to join.
These people are Russian military officers, they traveled to Salisbury, they did these things, they went back to Russia. They lied about who they are and why they went there. It doesn't really matter what the agenda of the people uncovering this is, as long as the information is valid. The question is, what should be done about it?
I wonder if the Russia rhetoric is just a Cold War 2.0 rhetoric designed to stimulate economic activity and innovation, whilst testing relevant bodies in the UK. Its nearly ten years since the SEC was caught watching porn before the financial crisis kicked off. Familiarity breeds contempt etc etc.
Oh come on, someone recently compiled detailed information on US military bases from the publicly available fitbit data of all the soldiers running round them. you can even figure out deployment patterns from it. Most militaries, even the big ones, are desperately naive about this stuff.
I know and so we have to trust them to make the right decisions when taking a country into war. Jeeze we really are run by amateurs!
During Cold War Russia hadn't annexed parts of European countries or left the radioactive trails all across town after assassinating their 'enemy of the state'.
"near identical looking"? Because, you know, either AA missiles are based on visual recognition AI or they're manned by special breed of operators who can distinguish fine details on planes 10 kilometers up in the sky.
