Brexit was, apparently, very popular with uniformed services such as armed forces, police etc, presumably border control too. I can imagine such disproportionate action is one way to feel good about your job and justify extra funding: just look at how many people we detained! Also, I’m not a paper pusher who waves people through, I regularly catch enemies of the state and put them where their place is.

In that respect, I suspect it is a popular policy among those who enforce it.
