Yes, it takes vigilance and a willingness to learn on the part of the parents, not parenting on intuition. It has to start relatively young and actively developed while at the same time, parents are learning.

As you said, there are some that are always a step ahead and we generally only learn when it 'happens to someone else'. This is why rather than thinking in the group, we should spend some time in the uncomfortable simulation of someone that means harm. The mind of the psychopath so to speak.

I see that this simulation helps prepare in numerous ways and gives guidelines of where we are strong and where we are not but most are unwilling to even think of terror, let alone prepare for it.
