I’m sure it’s just a job to her - not a calling. In fact, that mentality is responsible for a lot of what is wrong with law enforcement these days. And, it’s responsible for the anything to make it home safely tonight mindset. IMHO, of course.
You have hit the nail on the head (possibly). I see many young officers (male and female) who only consider this vocation to be a job until something better comes along.
I have performed CPR in the past in 110 degree heat, once on a drowning victim. Found out later she had a heart attack first.
The comments about looking for a dog to shoot or other juvenile attacks do not help. I wonder how long the officer had been on the job; how many broken bodies had she seen in person and up close? Unless you have been there and are able to detach, most people freeze.
