How covert is staring at someone’s shoes trying to identify slight variations?

>>ferros+hz
Well, don't stare at them. You know in advance that your contact will be walking down Merriweather Lane at 11:30am. If his shoes sport a single "X" near the bottom, that means the dead drop has the microfilm ready for pickup. If it doesn't have that "X", then try again next Tuesday.

If you see two X's in his lacing, the package is at the alternate drop site.

If he has 3 X patterns, you're burned! Make your way to the safehouse after losing any potential tails.

Glance quickly, agent, and keep moving.

This setup reminds me of operation PIMLICO:

> Every Tuesday, shortly after 7:00, a British MI6 officer would take a morning stroll at the Kutuzovsky Prospekt in Moscow. He would pass outside a designated bakery at exactly 7:24 a.m. local time. If he saw Gordievsky standing outside the bakery holding a grocery bag, it meant that the double agent was requesting to be exfiltrated as a matter of urgency. Gordievsky would then have to wait outside the bakery until a second MI6 officer appeared, carrying a bag from the Harrods luxury department store in London. The man would also be carrying a Mars bar (a popular British candy bar) and would bite into it while passing right in front of Gordievsky. That would be a message to him that his request to be exfiltrated had been received.

Just read the same in Wikipedia. This is extremely strange. Harrods bag and Mars candy in 1985 Moscow would be a telltale the size of Kremlin tower. Kutuzovsky avenue was a KGB owned turf, lots of Communist apparatchik lived there, including late Secretary General Brezhnev.

It reminds me a joke about Soviet spy arriving in Berlin and caughting stares from everyone around. What's wrong with my cover? Is something gives me out? Maybe it is a parachute? Or AK-47? Ah, it should be blue Slavic eyes! And he wears a sunglasses just in case.

I took it to mean that the MI6 agents were under diplomatic cover. It would not be strange for British diplomats to carry or eat British things, right? And it's also a decent defense against an accidental signal, since non-agents would naturally not have Mars bars nor bags from Harrods.

Like I said, Kutuzovsky avenu was (and probably still is) under massive state surveillance. English MI6 agent with diplomatic (under)cover will be spotted in minutes and their engagement and eye contact with highly ranked GRU officer will not pass below radar.

The whole point of this signalling scheme is to prevent eye contact, or any engagement. To an observer who's unaware of the system, it just looks like a local embassy official out for a stroll. Or doing some other routine thing that a lot of other diplomats also do. Meanwhile, Gordievsky is probably never even at that bakery. Or he is, but at random times that rarely overlap with British diplomats in the area. The only reason he would visit it at 7:24am on a Tuesday would be to signal for exfiltration. If and he's doing that, then the risk is worth it.

It's also only once a week that the timing is enforced, so they can vary things up throughout the week to hide that pattern in noise.

And the candy bar/Harrod's bag doesn't come into play unless Gordievsky needs an exfiltration. So it's not like they're noticing this weird thing where British diplomats always eat Mars bars every Tuesday. It would only happen once at most.

They know they're being surveilled. They can't change that. So they make their signal as mundane as possible.
