30 years ago, people had the luxury of saying "how could we have known?" when their child was abducted/raped/murdered.
They don't have that luxury, as hollow as it may actually be, anymore.
30 years ago, most folks lived in areas where they knew most of their neighbors, could easily recognize suspicious interlopers, and probably had faith that their local, state, and Federal government were honestly concerned about their safety.
Things have changed.
The thinking ("psyche" was my word earlier) has changed.
But the reality is that very, very, very few kids are abducted. So much fear over so little cause.
30 years ago there were places kids to run to if they were worried about a stranger. These days, many don’t want to be involved.
