"I find myself suspicious of the entire story about Brozman, though I admit, I have avoided any details."
Then perhaps you should get acquainted with the details before weighing in?

"I don't know if that is the case here, but the Brozman I knew never exhibited any sign of questionable behavior."
What kind of behavior do you expect him to have displayed in your company? Rubbernecking at 10 year olds as they passed? Saying "damn, that 12 year old had the body of an 8 year old" in casual conversation?
In the case of MOST pedophiles, people who knew them casually, even their friends, would express amazement and disbelief - "I never suspected, he seemed so normal" - your arguments hold no air. Especially when you yourself admit you are unfamiliar with the details.
