There, vandals also wrote the words, “Blood is on your hands,” on the sidewalk outside the Dallas Police Association building.

DPA President Mike Mata shared the following statement:

“The actions that took place at the Dallas Police Association and Dallas Police Headquarters tonight were not about protesting but a display of criminal activity plain and simple. Any message that pushes the idea of murdering police officers is not a form of protest, it is a statement of hate. The Dallas Police Association will prosecute the offenders to the fullest that the law will allow. The Dallas Police Association and its leadership will not be intimidated by those wishing harm on the men and women of the Dallas Police Department. We will continue to protect and serve the citizens of Dallas without hesitation.”

Late Thursday night, one of the groups that organized the protest, DSA North Texas Racial Justice Working Group, issued a statement to CBS 11 News:

The purpose of tonight’s event was to bring awareness to the 265-plus individuals who have been murdered at the hands of the police.  Blood is quite literally on DPD’s hands, which is why red hand prints and washable paint were put on DPD.”

Crews were seen beginning to remove the paint from Dallas Police headquarters shortly before 10:00 p.m.

Investigators are currently reviewing the surveillance cameras and are seeking witnesses.

Anyone with information regarding this incident can contact Detective Andrea Kunzler at (214) 670-5813.
