Local LEO is sympathetic to him and sandbagging.
If the local LEO being sympathetic to the other guy is not a red flag that you would be viewed as a bad guy if you attempted self-help, I don't know what is.
My attorney has tried to contact Commonwealth Attorney who is apparently too busy to reply over a two week period
You have a lawyer, what does s/he say about your rights?
I don't know anything about the law in your area, but it sounds like the other guy trespassed or maybe even committed a burglary. The police should take a report regardless of how they want to classify it.
The other thing I don't know is whether you have a castle doctrine or stand-your-ground law in your state on top of general self-defense law. That could come into play here if someone were to go on someone else's property without consent.
Don't let frustration cloud your judgment.
