I rather agree with you here Max. Hindsight is too easy. But the real problems is that that people are looking for anyone to blame
...often other than the person responsible (hindsight without blame isn't much of an issue)
If teachers are going to get blamed for failing to identify what is a complex, resource intensive area to identify & 'police'...which they likely have neither the resources, nor the training, nor the investigative power to determine whether the kid is fantasising, just troubled, or the real deal....then they are going to take the path that doesn't get them in trouble - such as treating all volatile writings or behaviours as threats, or as inidicators of serious threats.
The concept of Blame, in my view, is one of the most insidious, corrosive concepts in the modern world. I prefer to see the world as contributing circumstances and personal responsibility. As far as I can see, that is the only way to take responsibility for every part of who you are...and in relation to this thread - to properly problem solve (because once you 'blame' you tend to stop problem solving), and in the case of kids like your niece - to not treating everyone as if they were in the same boat (which happens when the individual contributing circumstances are not considered)
That said - if someone says, like in your example, they want to kill cops, then they are responsible for their own words & actions and there should be consequences (that again, look at the contributing circumstances, the decisions, and come to a fair consequence).
But we live in a world of blame because:
- media looks for people to blame (as it is much more emotive than considering the contributing circumstances, so it sells)
- people watch the media spin on events constantly, and end up buying into the concept of blame (then promoting it to others through blame, or accepting blame)
- sufficient blame culture has developed that people actually think it is normal, and right, to blame (again, I consider it a very unhealthy, corrosive concept)
- people expect perfection of others (though rarely of themselves. Lawsuits for 'negligence' against doctors are a perfect example. If ever there was a place made for mistakes, medicine is certainly near the top)
- people have little idea of the complexity of the things they expect to be solved / perfect (again, Doctors/Medicine is a leading example. Policing another)
- people see a 'system' rather than the imperfect humans that make up the system, and blame a system they expect to be perfect (which in effect blames the imperfect humans who are the system)
- people think money can solve everything (ie. throw money at it. Money can't solve everything)
- they think there is endless money in 'the system' (there isn't. The level of debt that keeps getting taken on tells us this)
...and in holding those ideas...support the concepts that support 'blame'.
This by the way, is not having a go at any poster here. It is something I've noticed growing more and more entrenched as the decades pass.
