Okay, so in my field of work (social work) we refer to that as "burn out" and there are many healthcare professional' members here (i.e., nurses...) who are familiar with it and can also relate. But see the issue is, whether a cop, a social worker, or a healthcare professional, when the work you do can/does affect human lives deeply and profoundly, it is the professional's responsibility to exercise self-care, seek assistance when/if needed and, if necessary, step away from the work, especially when/if there is a risk of causing harm to others. Step away.
One of my favorite college professors (Trauma & Abuse class) also counseled First Responders. Each week we had a different guest speaker; police officer, doctor, nurse, CPS social worker, firefighter, and an EMT. The common theme heard, regarding police officers, firefighters, and EMT's line of work, was the lack of or limited training and follow-up care they received for the repeated trauma they witnessed and experienced on their jobs day in and day out. We do need to do better - way better. We can't keep putting these individuals out there to do these jobs without providing them with adequate mental health care - with a huge emphasis on self care. Equipping LEA's with all the latest military-style weapons, body armor, and vehicles is/was thought to help keep them safer, however, like many gun proponents claim; "it's not the gun that kills but the person holding the gun." The same then should and can be said for LEOs holding/carrying/using guns; just who is the person behind the gun?
I don't think anyone here wants to see LEO's die; nor do we want to continue to see more civilians killed in what should be routine traffic stops/encounters with law enforcement. With that said, all of the explanations as to why and how LEO's go bad and/or make bad choices may be 100% valid, but the explanations alone can't be the be-all/end-all to the story. We have to do things different and better - for law enforcement and civilians.
