Thanks yknot.
For many the DFing effect only causes them to live double lives
I've seen this as well. I guess, in an odd way, it shows that the fear of DFing is present but may not be enough.
Most folks who rob banks do not think they'll be caught (at least I think that is what they think) so the possible prison sentence would have limited value as a deterrent.
It's kinda' like door locks...they keep out the "honest" people but not true burglars.
