The DA should lead an outside investigation and should do so if there is reason to believe a crime has been committed. Again, your perception...even of the "arrogance" (true or not) is based on biased views. There are still people who think Obama was not born in Hawaii. Does that mean he should continue to fund investigations that prove he was until there are no more questions about it?It's a lot about perception and smoke. This wasn't the first such case.
You're right, we don't know the facts. By keeping all of these serious cases in-house, Notre Dame will forever be suspect to cover-up charges.
To me, there's too much smoke for there not to have been some fires. If ND's president wanted to take some of these questions away he would let an outside agency lead some of these investigations. There's a lot of arrogance emanating from South Bend.
