The United States border with Mexico has been a chaotic border most of its existence. Mexican gangs, and even the Mexican army, have crossed it many times to raid American towns. And American military units have crossed the border south to track down and kill Mexican gangs numerous times. Criminals wanted by one government or the other have crossed over the border to get away from the law for literal centuries now. It’s a national past time for criminals, and basically no attempt to fully close the border has ever been fully effective. Different administrations over the last hundred years have deported millions of Mexicans who crossed the border illegally, often by using the military, but actually closing the border and keeping it closed has always been a very difficult process.
