What was your question? I took the printer and software coder questions as rhetorical. But if you want me to answer them here ya go.
If somebody knows about printers, is a software coder, or is a people manager. They certainly have more training than people within the organization that dont. Those people should be held to a higher standard than those who dont have those skill sets.
At this point I am not even arguing cops should be held to a higher standard. I'd settle for them being held to the same standard. What you are arguing is a cop should be held to a lower standard than an avg joe off the street when it comes to tense situations. If you are fine with that. I'd have to ask why?
What training do cops specifically get to deal with tense situations? That is how are they trained to deal with the tenseness of a situation and not the actual situation? For example, a cop responds to an active shooter. They are trained on how to neutralize that type of threat, i.e. what tactics to deploy and actions to take. They aren't shown how to feel or react mentally or emotionally. That is an individual thing. Only experience dealing with that kind of situation dictates those types of reactions, not training.
No, those people shouldn't be held to a higher standard. Just because someone knows how to code doesn't automatically mean they are an expert at all software. Actually its usually the opposite.
I am surely not arguing for a lower standard. I'm arguing for the same standard for cops as other citizens in that a cop knows no more how to deal with the tenseness of a situation better than you, me, or anyone else unless they are used to it. There is no training that makes a cop (or anyone) used to tenseness other than experience being in that situation. You are trying to hold them to a higher standard even though you claim otherwise.
