To expand on what
The way to go about it:
A child's family was murdered. From what little has been covered about them in the article, it could be said that they were "just regular folks".
"Why would anyone do this to them?"
ANY belief and/or community can be contaminated by what I'm about to describe. When a group winks at bad behavior, it can sometimes get very very very toxic.
Keep in mind, much depends on what is being winked at.
If I see a halloween prankster running naked down the street wearing nothing but a pumpkin head, and I know who it is, and don't tell, next year I might see three of them, and they might be in surrounding towns too. No big deal.
The problem is winking at drug dealers, bomb makers, lynchers, gang activity and other assorted trash.
If a community winks at trash, EVEN FROM FEAR, trash WILL accumulate. There are consequences to letting such trash grow, often paid for in the blood of innocents.
On a related note, this is why police corruption can be so horrible. Nothing promotes the acceptance of trash like corrupt cops, but that is for a different argument.
I can offer no easy or simple solution. It easy for me to type this, but it is still true: Until the COMMUNITY rejects the trash ROOT AND BRANCH, the trash will be a problem, and people will die.
