It's a far out idea, but how about 'electro-tagging' those on watch lists? At least then you would have some idea of where they are and who they are meeting. On a little less serious note, the tags could be explosive and if more than, say, three of them meet together, they all explode!! Neat.![]()
Explosive tags?! No Brisie that's what the terrorists want!
Maybe some kind of electric shock that causes them to involuntarily **** themselves.

elsewhere please..
