yes, remove incentives, any illegal who is detain by police or signs up for a government program will be deported. It’s like speeding. If we show a presence and intention to deport, some will leave on their own and fewer will come here. If you’re on the freeway next to a cop car, every one flows down.
That's why I keep an empty bottle in my car.
I hate flowing down on my seat!
(sorry, I had to do eet)
