San Diego (CNN) -- President Obama's critics have the right to be upset by his decision to shield from deportation, at least temporarily, some groups of undocumented immigrants. But they don't have the right to twist the facts, use inflammatory language and create confusion. They're the ones who are most confused. They don't appear to have the foggiest idea how the process would work. That's their own fault. They should have paid closer attention two years ago, the last time the administration did something like this, with the program known as Deferred Action for Childhood Arrivals. Simply put, Obama is using the executive power granted to him by the Constitution to reshuffle the immigration enforcement deck and prioritize deportations so that, for instance, the undocumented parents of U.S.-born citizens get a temporary "deferred" status and thus can't be removed for three years.

Navarrette: It's no free ride for immigrants; conservative critics wrong to suggest it is
If it's the latter, a large number of undocumented immigrants -- media reports have put the potential figure at 5 million, although the actual figure is likely to be much lower, given the response to @placeholder -- will be deportable once again.
