When something like deportation takes place instead of just arrest, and it begins to happen "after" the holes in the dike are plugged, I will then begin to believe that the ins and border patrol are doing anything other than a dance to preserve the appearance of doing something sort of like what we the people might expect them to be doing.
If they are arrested, and actually in violation of the INA, then they will be deported.
Don't blame the INS for doing what the President and Congress want them to do.
The blame is in Washington, not with the troops on the ground. You of all people should know this.
