DNA analysis is quite accurate as far as I know, but as you say, epigenetics deciding which genes are on or off adds a level of complexity. Predicting someone's behavior solely based on DNA is quite speculative.
As for criminal ID, yes, there are definitely limitations. We share DNA with relatives, possibly causing false positives, DNA can degrade, etc... Is there a specific finding you are referring to?

Yes, a recent appellate court in the US has found that DNA analysis is not exact enough to be totally usable. As you mentioned, close relatives very likely have the same markers for the characteristics they are looking at. They cannot positively say, “That one person did this because we know him from his DNA.” More physical evidence is needed to corroborate the DNA evidence.
