I recognize that point but here again there is a pretending that Bush suddenly started a program to allow Mexican immigration into the US.
Mexicans have been flooding into the US for decades. In many respects, borderbots are asking for a drastic change in US practices toward Mexico. This is arguably inconsistent with rule of law since the expectations are now disrupted and rules are enforced in a manner different from the past.
"PRETENDING"? No pretense here.
"SUDDENLY" ? The only sudden thing was the staged demonstrations by the in -our- face Mexican Flag waving episodes that shone the high beam of public focus on the problem that had been pushed aside for too many years.
"DISRUPTED EXPECTATIONS" and " MANNER OF ENFORCEMENT"? ... Do you really mean to say that just for the reason that a standard was neglected and lowered through amount of time, that a lowered standard should be allowed to persist?
