To US leaders: Please stop ignoring the Mexican cartels (and other organized crime)

In the news for the last half or more year has been filled with headlines of the horrors of the terrorist group known as the Islamic State, but while those are very horrifying and the psychotics of IS should be arrested or something, there are many other groups within the Americas that authorities and the public seem to be overlooking who are as bad or worse, such as, and especially I guess, the Mexican drug cartels, who have killed more people than IS. http://america.aljazeera.com/opinions/2014/10/isil-vs-mexican-drugcartelsunitedstatesislamophobia.html But also there are plenty of organized criminal groups who still walk around, such as the Yakuza, the Triads, the hell's Angels, the Outlaws MC, the Mongols MC, the Latin Kings, the Israeli mafia, the Korean Killers, MS-13, the Russian mafia, Aryan Brotherhood, , I could go on and on, but that's not the point. The point is these groups are still around, even as crime rates have dropped in years, but they're still around, and going about with their crimes and dealings. So to pundits, persons in power,  and other US leaders, please stop ignoring all these guys who are dangerous criminals and syndicates.
