One other thing I would add is, I suppose if you don't give out any details about a crime and what occurred, it would be easy to lump it all into one and not sense any kind of 'trend'. For example, what on earth had a 16 year old boy been exposed to in his life to make him act in such a way (I will apologise that I haven't seen the details you've read/heard about this week but I am guessing they were pretty horrific). I think personally, that, although I find these cases frightening and upsetting, I would rather know if something sinister is on the increase. Maybe due to an increase in availability of porn/violent programmes/broken homes/poor schooling/sexual abuse/drug availability.
If we are not aware, how can we comment on, for example, legalising cannabis? Or availability of online pornography. On the dark net there are snuff videos, child pornography. If we don't know what goes on, we can't lobby or display our disgust at how this affects young people, can twist their minds and so on.
I am not an expert, I don't have the answers but I do like to know what I'm dealing with in life. I would probably be much happier if I didn't know these things and I respect anyone who chooses not to put themselves through it of course.
Sorry DH is getting irritable. Waiting for me to go out for some air for first time since last weekend but will return to thread later as it's very thought provoking.
