Perhaps one of the key points missed in this discussion, particularly when it comes to the questions being posed about Tom Armstrong's judgement in wanting to help these men (convicted sex offenders who have done their time), is this.
I recall that Armstrong's original desire was to house these guys together in a transitional housing type arrangement from which there would be some supervision and support given to them as they foundd their way back into society. Instead, due to the uproar over the very fact of them living together in a setting where they could have been supervised and supported, they are forced out on their own.
Of course there is no way to know for certain that the outcome would have been different had Owen remained in a group housing setting, but at least then Armstrong's detractors comments would carry more weight.
