As far as I'm concerned they were Mexicans not Americans. They've lived there by choice for generations and they originally went there in order to evade American law so they were really more American than any other native Mexican citizen. Mexican breed and Mexican born. Therefore let Mexico take care of it because it's really not our problem.
Of course, it is our problem!
It emphasizes the critical importance of securing our Southern border with a wall/fence/barrier, patrols, drones, cameras, and sensors. Mexico had 33,000 murders in 2018. Imagine if we had 75,000 murders?
We should immediately declare that the Mexican Cartels are terrorist organizations and begin the same level of attack on their organization in the United States.
The President of Mexico has said that they need to combat the Drug Cartels with HUGS NOT BULLETS. Is he a part of the Cartel? Which one?
