For my 2 cents worth ...
This isn't likely going to end up as a "right or wrong" issue, but a
smart or wrong issue.
People like to read into things whatever they want to see there.
Yep, always
at least 2 sides to every situation (because some folks on any particular "side" may not be able to remain consistent where trying to explain something after things have gotten squirrely).
Local LE may not see either "side" as being "right", but various shades of "contributory wrong". The old saying of "2 wrongs don't make a right" still has meaning and relevance.
Dunno what "blocking a dirt road" means without being there to see it. Private property road or unimproved county road? It can matter.
Things in the country might be shrugged off as a civil matter ... until somebody does something "criminal enough" which makes the local LE decide "enough is enough", and somebody gets stuck with
avoidable legal trouble. Might not be the "side" that expects it, or which started it, either. (Or which "deserves" it, depending on which perspective holds sway at any particular moment.)
Don't remember enough of previous threads/posts to have an opinion regarding OP's situation. (Situations?)
Get some legal advice, meaning consider speaking to not only the local sheriff, but an attorney who practices in this area of the law. Dunno if that may mean also talking to attorneys who specialize in land use issues, as well as civil disturbances and property disputes. Only you really know your situation, so only you can start looking for answers other than in an online gun enthusiast's forum.
Once you know your options, as well as you might be able, then be prepared to discover that there may not be a perfect answer (in the manner you desire) to your situation.
Neighbor disputes can be many combinations of unique and nasty.
Sometimes even the cops can only sit back, powerless to "do something" demanded by one or another "side", hold their breath, and wonder which "side" is finally going to cross the line where it's all downhill after that.
You have my sympathy and empathy, but I can't pretend to be remotely able to offer any sort of advice. Good luck.
