The recent officer-involved shootings are a reminder of the danger that police officers and sheriff's deputies put themselves in every day.
And for the husbands and wives of these officers, these latest incidents are re-igniting their fears of getting that dreaded phone call.
Julie Crane is married to Phoenix Police Officer Ken Crane, and lives with that fear every day.
Ken Crane has been a police officer for 24 years. There have been many nights when Crane was away, and Julie heard news of an officer down.
"You immediately want to find out who it is. First of all, what agency, is it Phoenix, what city? And then where, what precinct, is it the precinct that your husband or wife works at," says Julie Crane.
"You're out working on the street when it happens, I think the gut reaction and instinct for most officers is you want to go to that scene and be a part of that scene, to help, to do whatever you can," says Ken Crane.
Despite being veterans of the lifestyle, the dangers of the job never cease to amaze them.
"As cops we get very good at putting this psychological wall up in our brain, and I think even spouses get good at that when the husband goes out the door. We all know the hazards of the profession, we know we could get involved in something like that," says Ken Crane.
"You can't totally divorce yourself from it, but you have to put that wall up because if you don't and you just dwell on that it will literally consume you."
The Cranes say communication is key, and support groups are a great resource.
