If this issue of line-jumping is much more important to you than stopping terrorists and criminals, then feel free to speak your mind; the naughtiness of line-jumping does deserve some measure of thought but not nearly as much as our need to separate the productive and peaceful from the nefarious and criminal. It's not an either-or issue, as the duty to obey laws can be satisfied with a monetary fine or other.
Usually we see the anal-retentive types smugly driving at the speed limit in the fast lane, imperiously demanding that any law-breaking speeders maneuver around them.
If this issue of line-jumping is much more important to you than stopping terrorists and criminals... I was discussing, illegal immigration and the problems it's causing, not terrorism and what should be done.
