“Rounding up illegals” implies going out and looking for them.
The survey question was simply about verification during traffic stops, no different than the standard check for open warrants. So it is more “holding onto illegals after they’ve committed a crime” than “rounding up illegals.”
Of course, I actually DO favor “rounding up illegals” via a bounty system utilizing retired LEOs and charging the costs to employers and landlords who failed to verify immigration status.
What the hell you think they are gonna do when they find illegals at a traffic stop if this is implemented? Let them go? No, they are going to round them up.
