A Reflecting Pool that has long enticed visitors now gains police scrutiny under Trump

The Lincoln Memorial Reflecting Pool is many things.

Murky. Peaceful. Stinky. The backdrop for protests, vigils, celebrations and stunning sunrise photos. Beset by gnats and algae. Scenery for a run. A key part of the capital’s carefully designed monumental core. The location of an iconic scene in “Forrest Gump.”

One thing it’s generally not: a strictly enforced police zone.
