Ethics online: Is there a difference?

Ethics online: Is there a difference?:
A teacher says that he isn't giving a test grade back until Monday, because he hasn't finished grading them all," a participant wrote in an online forum at collegeconfidential.com last week.

"You walk by his desk and notice that yours is done and on the top of the stack.

"Would it be unethical to walk close to his desk on the way out and sneak a peek?"

This is one of hundreds of hypothetical scenarios rippling across the Web after it was revealed that some business school applicants - most of them aiming at Harvard University - exploited a technical glitch to get an early peek at their pending decisions online.

-----------------

Sneaking a peak without permission would be ethically questionable, because until a professors grades are returned, there is no way of knowing that they are final. beyond that it is 'snooping', and that is rarely correct action, though sometimes when the consequences are dear enough it might be, but for grades... it isn't

in short, i think what harvard, and others universities did is perfectly fine.
