Poland introduced temporary controls on its borders with Germany and Lithuania on Monday in an effort to stem what the government says is an increasing number of undocumented migrants crossing from the north and west. The re-imposition of border checks is just the latest example of how mounting public concerns across the European Union over migration are straining the fabric of the bloc’s passport-free Schengen zone.
Problem with the border checks is fundamental though.
Either they are arbitrary and by that of course useless in achieving the stated goal, mostly just harassing people who look wrong for traveling across the border, or they have to inspect every truck, car and person crossing, sabotaging European logistics more than any Russian parcel bombs could.
