Not to plug but here is Vice News coverage of the el chapo escape along with a more detailed view of how they construct the tunnels. <a href="https://www.youtube.com/watch?v=Kh3RHV5G1Fc" rel="nofollow">https://www.youtube.com/watch?v=Kh3RHV5G1Fc</a>
To quote an old adage: "...interprets it as damage and routes around it."<p>This seems to apply more to black market trade than the modern internet. Information can't be stopped permanently, but the usage of various services on the internet can be made less convenient and curtailed, even by 2nd and 3rd rate governments, if only for awhile. Meanwhile, the most powerful state on Earth can't stop the inflow of illicit drugs.
The number of tunnels seem excessive, I don't know the drug numbers but let's use people.<p>A tunnel large enough to walk though could send 10 people a minute without problem. While 24/7 would be near impossible to achieve, it’s 600 people an hour, 14,400 people a day, and up to 5,256,000 people per year.
I was hoping for an explanation of how they are able to pinpoint exactly which direction to dig and come up. I mean.. coming up into a 2 foot square from 35 feet underground from a mile away isn't something you guess at. GPS signals don't work underground do they?
