No Concrete Reason

Barriers to buildings Are familiar to us here. Right after 9/11’s shock, They started to appear. But just this week I noticed Something added to the stock – At a stairway that I frequent There’s a jumbo concrete block. To be fair, the stairs are leading To the mayor’s stately manse So protection is important; They’re not taking any chance. Though I do not get the placement Of this ugly concrete slab For no vehicle could climb the stairs – No car, no truck, no cab. Some authority decided To keep terrorists at bay, They’d plop down a blob a concrete And then all would be okay.
