But First Assistant Chief Charlie Cato defended the decision as having been made to ensure public safety, the Dallas Morning News reported.
The police escort had outraged Dallas and Lancaster police officers, as well as others, who said it was disrespectful to provide a police escort for a cop killer.
"The decision to utilize these resources was unplanned, and the sole purpose of their presence was to address the immediate public safety issue," Cato wrote in a prepared statement, according to the article by Morning New writer Tanya Eiserer.
"We recognized there might be concerns about our decision," Cato wrote. "I truly regret and apologize to anyone who has been offended or hurt by this decision. Please know that neither I nor [Deputy Chief Julian Bernal] intended in any way to be disrespectful to any fallen officer."
The Morning News earlier had reported that Bernal had issued the last-minute order for the escort.
