The El Paso Walmart shooter was aiming at/for Mexicans and Central Americans waiting for their asylum hearing, 22 killed. The San Ysidro 1984 McDonald’s shooter targeted Mexicans, 26 killed.
Who can say that it wouldn’t ever happen in Calexico’s Walmart or McDonald’s? No other city in California has a larger percentage of Mexican residents. A “Real American” could easily accomplish his mission to kill only Mexicans.
