The solution to mass illegal immigration – mass legal deportation

It should be obvious, right? Note: None of the below applies to LEGAL immigrants. Here’s an analogy. Someone breaks in through the window in your lounge. What do you do? Shoot them dead on the spot (“stand your ground” States), arrest them and call the police, chase them away and repair the window, or, as per current US, UK and EU behaviour, throw the elderly relative, veteran or kid out of a bedroom (doubling them up in another bedroom) feed the criminal, put the criminal on your health plan, give him access to all of your house and give him an allowance?
