"Houston Police Chief Art Acevedo said a senior officer shot while serving a narcotics warrant at a home later passed a note to him at the hospital saying he had to jump in there when other officers were down.... According to Acevedo, once two officers were down and a third was shot, the other officers left their cover positions to pull their fellow officers out of harm's way.
The 54-year-old senior officer breached the door when he knew his partners were down.
"I had to get in there because I knew my guys were down," the officer later said in a note to Acevedo.
"That just speaks volumes as to what this man... just his courage under fire," Acevedo said of the officer.
This was the third time in the officer's career that he had been shot. He was shot before in 1992 and 1997."
