IMO, the "incident" 5 years ago would be less of an issue if you could blame it on youthful indiscretion. The problem is that you were 31 when it happened.
Now, as with all blemishes in one's past, the more distance you can put between you and the blemish, the better. With that said, many agencies/departments have age cut-offs and you may very well be past these before you have the necessary time between you and this incident with which you are concerned.
Who knows, different places have different standards. You may be able to find one that does not put too much weight on the problems in your background. The economy will not be your friend, though, as there is more competition for every job out there.

was'committed'."
