Suff, you might have got the wrong end of the stick. The couple felt 'violated' not because they were arrested based on 'information' from the public, but because they had their names, address and pictures splashed all over the papers in a media trial. Innocent until proved guilty, and all that.
In today's society it would not have taken much for some nutter(s) to 'go after them' in some sort of revenge for the disruption caused; and the papers gave them all the information needed to get to the couple.
