re: As a practical manner, how are we going to remove all the illegal immigrants?

It doesn't matter how they are removed. I really don't care if it looks like the Bataan Death March. They need to go.

As a practical matter, though, here is what will happen: once the illegals get the message that they are not welcome and will be targeted for deportation, a large percentage will self-deport.

The woman who cleans our house twice a month (she is legal) has a nephew who went back to Colombia last month on his own rather than go through the hassle of being deported. I seriously doubt he will be the only one.

Also, we need to crack down on the businesses and individuals who are hiring these people. Once the jobs dry up, there will be a virtual stampede of people heading back to their countries of origin.
