Meet the Zetas: the most notorious Mexican drug cartel ever to share a name with a college
[16]
sorority.
[17]
But don’t worry, it’s easy to tell the difference between the two: one is full of
[20]
conniving, ruthless, cutthroat sociopaths clawing their way to the top of a rotting
[24]
hierarchy, and the other is a drug cartel.
[26]
When you think of Mexican drug cartels, you probably think of gun shootouts or cocaine
[30]
snowmen or Netflix series’ that people keep telling you are good but you just don’t
[34]
have the time to get into.
[35]
You probably don’t think about communications infrastructure—but, you see, that’s why
[39]
you weren’t the most powerful drug cartel in Mexico in the mid 2010s.
[42]
Well that and because you’re a nerd, which I know because you’re watching this video.
[46]
The point is, while you were busy spamming my submissions form with brick video requests,
[50]
the Zetas were building a secret, private cell network that stretched across nearly
[55]
all of Mexico.
[56]
The system starts with low-level operatives working on the ground who are called halcones,
[61]
which Google Translate tells me is Serbian for halcones.
[63]
The halcones patrol the streets and suss out important information—the movements of soldiers,
[69]
location of Mexican police, recaps of Downton Abbey, and actions of rival cartels.
[73]
Halcones each carry walkie talkies or radio cell phones set to specific frequencies, which
[78]
are selected after analyzing the local radio spectrum and avoiding any radio frequency
[82]
being used regularly by people like cab drivers, police, or scrappy 80s tweens.
[87]
Once halcones have a message to convey, like “police are headed north” or “soliders
[91]
are asleep,” their walkie talkie frequency will be picked up by antennae the cartel has
[95]
constructed all across Mexico: in trees, on rooftops, on existing communications infrastructure,
[100]
or on whatever other tall pointy thing they can find.
[103]
The nearest antenna will both receive and transmit the message, but if it needs to travel
[107]
further than the immediate vicinity, it’ll be amplified by repeaters, many of which are
[111]
owned by communications companies like Nextel, but which Zetas managed to hijack and reprogram.
[117]
Basically, repeaters do for radio waves what this channel does for quirky Wikipedia entries:
[121]
it repeats them much more loudly and aggressively.
[124]
Specifically, the Zetas use duplex repeaters, which are able to both receive and transmit
[129]
messages by using different frequencies for each.
[132]
If you’ve ever tried using a cell phone before 2005, you’ll know that getting widespread
[135]
coverage isn’t easy, and that was certainly the case for the cartel, especially considering
[139]
that they didn’t have this guy to test the network.
[142]
While installing antennae and repeaters was relatively easy in cities, to make the network
[147]
truly cohesive, it had to stretch across miles of jungle in areas like Veracruz, and if there’s
[152]
one thing I know about the jungle, it’s that it doesn’t have a ton of AC outlets.
[155]
That meant that not only did cartel engineers have to build cell towers to get the antennae
[160]
and repeaters high enough—towers which, by the way, they painted green for camouflage,
[163]
as green famously cannot be seen by the naked human eye—but they also installed solar
[167]
panels to power the equipment, mainly because they can operate independently, but also because
[172]
even murderous criminals know not to support the fossil fuel industry.
[176]
While some of the local networks are overseen and managed by semi-autonomous regional command
[180]
centers, the entire system is linked together by a communications headquarters, which we
[185]
believe was located in a radio shop called V&V Communications located in McAllen, Texas.
[190]
It’s a logical spot: nondescript, near the border, running a semi-legitimate business,
[194]
and, according to Facebook, it has a five star rating and 108 likes, which is by far
[199]
the most likes I’ve ever seen on the Facebook page for a potential drug cartel communications
[203]
headquarters.
[204]
The command center uses commercial equipment from Motorola that can connect cartel members
[208]
in faraway local networks who need to communicate, as well as monitor thousands of the walkie-talkies
[213]
at once, changing their communication frequencies as necessary and deactivating them if a halcone
[217]
is captured or killed.
[219]
For security, the cartel runs messages using what’s called a digital inverter, which
[223]
distorts voices.
[224]
I’ll demonstrate now, while I tell you which YouTube creator I hate the most.
[228]
It’s *distorted voice.* Man, it was good to get that off my chest.
[232]
The system was also robust enough that if certain towers were knocked down, info could
[236]
be routed through others in the network.
[238]
Basically, it was about as good a cell network as you could get—and because the whole thing
[242]
was illegal, they didn’t waste any money on TV ads with multicolored maps or a spokeswomen
[247]
the internet develops a creepy obsession with.
[249]
The system was masterminded by a man named Jose Luis del Toro Estrada, who led something
[254]
of a cartel geek squad, mostly made up of kidnapped communications experts.
[258]
At last count, 36 engineers have been kidnapped, and there isn’t anything funny about that,
[263]
so instead here’s a picture of a giraffe and an elephant who are friends.
[267]
In the end, the Zeta’s network covered nearly 500 miles of the Texas border, and went another
[271]
500 miles into Mexico, before it was ultimately discovered by law enforcement because of course
[277]
it was, because that’s how we know about it.
[279]
I mean, you didn’t think a YouTube channel that mainly covers weird geography quirks
[282]
and legal loopholes using outdated memes had gone undercover and unearthed a major criminal
[286]
conspiracy, did you?
[287]
A single 2014 operation managed to unearth “167 antennas, 155 repeaters, 71 computers,
[293]
166 solar panels and batteries, 3,000 radios and Nextel push-to-talk phones, 525,600 minutes,
[298]
and of course, 500 Days of Summer.”
[301]
These days, the Zetas are much less powerful, but are still operating, which means it’s
[306]
unlikely their network has been completely crippled.
[308]
So if any Zetas are watching this video and are mad at me, I just want you to know my
[312]
name is Devin Stone, I look like this, and any complaints should be directed to the comment
[316]
section of my channel LegalEagle.
[318]
If you want to reprogram communications infrastructure to serve your illegal drug cartel, the best
[324]
place to learn how to do so is Brilliant: the problem-solving based website and app
[328]
that helps you achieve your goals in STEM learning.
[331]
If there’s one thing I’ve learned about learning, it’s that learning to learn doesn’t
[335]
have to be hard.
[337]
That was confusing, but Brilliant is straightforward: it breaks down complex topics into easy-to-follow,
[342]
bite-sized chunks that’ll engage you with storytelling, coding, interactive challenges,
[346]
and problems to solve.
[348]
And if coding isn’t your thing, you can learn to do a whole host of other stuff: like
[351]
building neural networks, mastering machine learning, or even just brushing up on geometry.
[356]
Even if you’re a person tight for time, you can complete their daily challenges to
[359]
learn a little bit, every day, in the small, free moments of your day.
