Even if that were true but it's not that would have had to happen long ago and those people are all dead now. Just what Americans are doing that today? If some are they will be held accountable by the Mexican government and rightly so. That doesn't justify Mexicans running rough shod all over our country at will today. Keep trying to justify illegal immigration into our country today. It's fun to watch.The Spanish and Mexicans had laws regarding immigration. The gringos chose to break or ignore them. The flapping noises you hear are chickens coming home to roost.
