Except for the shooter, no one was killed in the June ambush. Now in a single incident, Dallas has lost five officers. That’s as many as the department had lost in the previous 12 years, based on figures Brown cited in the February interview with the Observer. (In the latest incident, four of the officers killed were members of the Dallas PD; the fifth worked for Dallas Area Rapid Transit, which is a separate agency. )

Like the gunman who shot up the police headquarters, the sole intent of the suspect in the latest attack appears to have been to kill cops. That’s what he told police negotiators before he was killed by a police bomb detonated by a robot early Friday. Indeed, despite the thick crowd,  the gunman hit only two civilians. All the other victims were uniformed officers.

On Friday, Brown seemed frustrated. “We don’t feel much support most days,” he said.

“Let’s not make today most days. Please, we need your support to be able to protect you.”

The June attack had already spurred a debate of how the city’s protectors could better protect themselves. The police department started requiring anyone entering its offices to go through a metal detector, and there were plans to install bulletproof glass. In December, the city hired a consultant to assess safety at police installations and recommend ways to improve it. That’s the kind of expert advice that the police department is used to doling out to others, the Observer pointed out.

Neither the police department nor the city immediately responded to requests for comment on the status of those efforts.

At the end of the day, Brown said back in February, extra security will only do so much to help, because the only way to stop an attack against police is for police to engage the attacker.

“It messes with your psyche that when you come to work you need to have your head on a swivel walking between your car and the building,” Brown said in February.

That’s a workplace hazard that Dallas police won’t be forgetting anytime soon.
