The infamous group Anonymous pledged war against The Zeta cartel in 2011 with announcements that they had names, and even personal information about the cartel members. Unfortunately, anonymous decided to back down due to threats of aggravation. Though, in the end the hostage was released the cartel has killed numerous internet bloggers/reporters, and has kidnapped hackers to perform black-hat cyber attacks against targets...

It all seems to come down to the amount of resources one has to invest in such an effort. The various law enforcement communities are fighting with the "latest" technology but, the cartels are right there with them if not below or above them...

In the United States, the latest defense may be the use of various autonomous robots such as, submarines, boats & drones.

Unfortunately, similar techniques are being applied by the cartels to thwart the deterrents. It seems only obvious because, its less weight, and less people = cheap.

Like Autonomous ultralight UAV. https://news.ycombinator.com/item?id=4415508

Autonomous ROV/USV Submarines without life support systems must be cheaper.

Just mischievous robots in general, https://www.google.com/url?sa=t&rct=j&q=&esrc=s&...

Think on it.
