Well when you enter a country illegally and try to take advantage of all the benefits said country has without taking the steps to become a naturalized citizen like the law abiding immigrants than yes you will be referred to as an illegal alien. And just so you know the definition of alien is "belonging to a foreign country or nation" so I fail to see the point you are making. And your second statement has no factual basis whatsoever. The main reason why Hispanics and Blacks come into more contact with US police is because of socio economic status not race as socio economic status is the contributing factor to crime.
