These cases just don’t get national news coverage. A concealed handgun permit holder saved a police officer who was being ambushed in Arizona at I-10 in Tonopah (January 12, 2017). From the UK Daily Mail:
The trooper was shot at least once near his chest and fought to the ground by the suspect. The man was on top of the officer and ‘getting the better of him,’ slamming the trooper’s head into the pavement.
That’s when the passerby spotted the altercation and asked the officer if he needed help. The officer said yes, and when the suspect ignored the passerby and continued attacking the trooper, the Good Samaritan shot him dead. . . .

Deputy First Class Dean Bardes, a 12-year-veteran, was working a crash at mile marker 126 when the suspect came upon him, causing Bardes to pursue him at high speeds, according to multiple sources.
Bardes and the suspect exited their vehicles at the Corkscrew Road exit and a fight started, sources said. The suspect was armed, Bardes told his supervisors, according to sources.
The passerby, who had a Concealed Weapons License, exited his vehicle and told the suspect he’d shoot him if he didn’t stop beating the deputy, sources said.
After noncompliance from the suspect, the passerby shot the suspect three times, sources said. The suspect later died. . . .
In this case, Thomas Yoxall, 43, a maintenance supervisor, used his permitted concealed handgun to save the life of DPS Trooper Edward Andersson. Yoxall had his gun rights restored in 2003 after he successfully completed probation.
Other cases of civilians using guns to save the lives of police officers are available here.
Note: Not only can civilians directly save the lives of police officers, but the fact that there are civilians carrying concealed handguns who are unknown to the criminals makes it riskier for those criminals to attack police.
