Or simply unethical?  Maybe DD would not take a 'confession' gained 
unethically by means of legilimency but rather choose to let 
the 'accused' either prove themselves in some way or own up.

I suspect many of us feel that Snape has 'had it in' for Harry and 
maybe DD saw that and refused to allow himself to be swayed by someone 
who was trying their hardest to prove Harry was not the person DD 
trusted.
