Pensieve in Court & Magic Eye

Hi all,

I just have a couple of questions about something that has puzzled me 
for a while now:

(1) How reliable is the use of Pensieve in wizarding court/trials?  I 
was wondering the possibility of HArry reserving his memories of 
Dementors attack in Privet Drive and showing that at his hearing.  
Maybe it is reliable when proving the Hear-Say type of evidence?  
What skills does it take to be able to use Pensieve?  Also, can a 
wizard alter his/her memories before reserving them in Pensieve?

(2) How does one acquire a Magic Eye?  Even the greatest Wizard of 
modern time Dumbledore doesn't have it (the Leaving Fest at the end 
of GoF) and it clearly has its advantages, helping Barty Crouch Jr 
outsmart DD himself.  Do you think it is a Dark Art?  Then perhaps 
Voldemort has a pair of blue-electic buzzing eyes too?

Any thoughts/idess/suggestions?
