You are a border patrol agent assigned to a city located near the Arizona-Mexico. one day you see a truck loaded down with people who, from your experience, look like they just arrived after crossing the Mexican border, which is located only 20 miles away. ( in other words, based on their clothing, hairstyles, and mannerisms, they do not look like U.S. residents.) You stop the vehicle and begin asking questions. however, you cannot get a coherent answer because none of the vehicle's occupants speak English (and you do not speak Spanish). you take the occupants of the vehicle into custody because you suspect, based on the totality of circumstances, that they are illegal immigrants who just crossed the border. Was the arrest valid? Explain
