Anti-abortion demonstrators painted the phrase “BLACK PREBORN LIVES MATTER” on the street outside Planned Parenthood in downtown Baltimore, spelling out in 10-foot yellow letters Saturday a message they said is in keeping with the “Black Lives Matter” theme that has helped fuel anti-racism protests across the country this year.

Students for Life of America joined with members of The Frederick Douglass Foundation and Human Coalition Action, an anti-abortion nonprofit group, to organize and carry out the painting. Fifteen people began working with buckets and paint rollers at 5 a.m. and completed the mural within an hour and a half.

The paint is tempera, which washes away with rain.
