It's always the innocent who get hurt by these people. I am reminded of a saying that I once read;
"When the stone falls on the jug, it's unfortunete for the jug.
When the jug falls on the stone, it's unfortunete for the jug
It's always unfortunate for the jug."
I for one am doing everything I can to inform people in the area where I live about these people.
I hope I can prevent some, at least, from getting involved and getting hurt.
