Lol illegal crossings caught / reported. The majority of illegals come over legally and just overstay their vacation, education, work, business, or deplomat visa. Why bother crossing illegally when you can just request a vacation visa or day visa and just disappear into the country. (Yes those without passports will have to sneak across but it’s way easier than the Trump administration will have you believe.) Yes thousands get caught but millions go back and forth without. Yes most go back without needing the US government to force them.
