The less inflammatory synonym for "camps" is enhanced ICE detention space, but that doesn't have the same ring.
The point of detention, by the way, isn't to hold people, it is to remove them, as Trump noted the other day.
Of course, these people must be removed. We need to eliminate the problem. This is the Final Solution.

Don't worry, this is only for illegal aliens. We don't know how many there are, who they are or where they are, but you can be certain nobody will be detained by mistake. Just make sure you are carrying your Identity Papers at all times.
