Has anyone ever thought through this promise? He promises to remove the worst of the worst criminal illegal aliens, right? Who are these people?
They are the murderers, rapists, drug dealers, gang leaders, and other hard core criminals. These are criminals currently in prison (where else would you easily find criminal aliens on day 1?)
So what Trump is promising to do is release these murderers, rapists, drug dealers, gang leaders, and other hard core criminals from prison and drop them off across the border (yes, drop them off, that's how it works, there are tent cities at various border points where people who are currently deported have to live until they are processed).
So he is dropping off these murderers, rapists, drug dealers, gang leaders, and other hard core criminals into an unsecured tent city (in cities populated by a lot of innocent Mexican citizens too), right next to a border he claims is not secure so they can easily come right back in.
It sounds like a low budget Suicide Squad sequel.
