So the big question is if would have been better to strike fast, silently gain more intel och strike in some kind of statistical analysis maner to not blow their cover á la Alan Turing and the enigma
Well, in hindsight, this is not a big question any more, they are all in jail now and will drag most of the supply and micro distribution chain with them.
More careful actors are still out there and conducting business as usual.
I have read a book on one of the main Italian groups, they have very efficient micro storage procedures to avoid big losses and at least the higher ups will not use phones or computers, they will meet in person. They have or used to have rules of conduct which are very strict, like, stay home with family and don't be seen in bars etc. The opposite of the green horns flaunting the cars and watches, or the Turkish guys wife documenting their lifestyle on Instagram up until yesterday.
Sure, mass arrests happen in Italy as well, and some other countries the whole network works different.
But using phones is too dangerous and it is avoidable to run efficient logistics.
Not only for traceability, but a compromised or confiscated phone will have a lot of let's say problematic evidence on it.
Even the Mexican and Colombian groups operate from remote areas, even if affiliated with some parts of governments.
I think the usage of digital devices is just lazyness, another attribute like the flaunting of the illicit gains.
