I disagree if you mean Muslim men that are under scrutiny. I don't think Bush would face any heat at all except from the loony tune left. If you are talking about all illegals then yes, it would be a nightly presentation of the infamous "Elian,JBT" photo. That is not about to happen.
The only one (of this map-on our soil) the -Barney Fife FBI- managed to nab was foiled. If it is only the leftists and the human rights weirdos that would scream if he booted em out and sealed our borders to any more of any potential terrorist, then why is he not doing it? He seems to have the gonads, why is he not?
I believe it is because of our CIA/Immigration/FBI laws and politically correct standards. As crazy as it sounds these terroristss have rights and if a President usurped this in the name of national security before the next horrific event would he lose votes?
