"We're going to put together a plan that we can do every single weekend, and everyone in Dallas is going to be able to see what we're doing," Comeaux said during a hearing examining the department's preparation and response to the Halloween night violence. "And it's going to be very consistent."

The hearing followed a deadly Halloween in Deep Ellum, when three separate shootings left four people dead and 15 others injured.

Deputy Chief Devon Palk, who commands the Central Patrol group, said 58 officers were assigned to the district that night, including 11 hired by the Deep Ellum Foundation. That was roughly 20 more officers than the previous weekend, Palk said.

Comeaux defended the staffing level. "We definitely had the proper staffing, you know, it was just a bad night," he said.

The violence included a shooting in the 2600 block of Elm Street that killed 20-year-old Isaiah Boling. In a separate shooting in the 200 block of South Crowdus Street, three people were killed: Kenesia Scott, 21, Anthony Martin, 25, and Unique Benjamin, 28. No arrests have been made in either of those deadly shootings.

In a third shooting, David Yancy, 31, was arrested Nov. 4 after admitting he fired into a crowd from a parking lot on Main Street, according to police. Seven people were injured in that shooting.

Council member Jesse Moreno, whose District 2 includes Deep Ellum, urged city officials to stay open to additional safety measures even though the district's safety plan was updated seven months ago. Moreno said reinstating a juvenile curfew was among the most common suggestions from business owners and residents.

Dallas police said state law prevents cities from enforcing juvenile curfews, meaning any change would require action by the Texas Legislature.

Moreno also asked whether police could establish a physical security perimeter around Deep Ellum, where streets provide access from multiple directions.

"What would a perimeter, a physical barrier perimeter around Deep Ellum to monitor entry and exit, look like?" Moreno asked.

"It's not easy," Comeaux responded. "You put a perimeter around Deep Ellum, you're talking about probably increasing the manpower by 20 to 30."

Comeaux said the department is already working with parking lot owners on measures that would allow police to issue trespassing citations to people who are loitering.

The discussion comes as Deep Ellum businesses have weighed safety concerns against slower sales in the wake of the shootings. The district's safety plan, which sets rules for late-night venues, was last updated in the spring.
