My neighbour is an abusive alcoholic nutjob. I have had a couple of run ins with him, once when our dogs barked and he came into the pub in the village and screamed at my husband calling him a cunt and a dick head, we went and got cctv at that point to se if the dogs were making a nuisance, hundreds of pounds later we have hours of footage of our dogs sleeping however it did pick up a dog barking but it was his other neighbour on the other side.. 
no apology.
Then he took it upon himself to complain that our log burner was making his kid sick. The log burner that hasn't been on for 5 months.. I had to send him a photo with the time and date of the photo of the burner off before he stopped texting me. Turns out it was his neighbour on the other side burning stuff in their garden and he had the windows open..
About a week ago he asked me to make sure the shared gate is closed because our other neighbour is complaining it was banging in the wind, fair enough I said I would. Last night I must have not closed it properly as the lock is really stiff, he walked past it from the pub and hammered on the door screaming that I'm a fat retard and fucking cunt. I called the police and they had a word with him, they've also referred him to social services because he was so drunk and his kid was in the house.
Aibu to get a protection from harassment order, and to block him on everything? he's an absolute state. He's in sole charge of a child and is drunk and abusive all the time. He doesn't own his home, we do. It's a bit more complicated than just going to his landlord though as he technically doesn't have one, he's living in the house of his dead partner and it's owned by her family. Aibu to contact them and tell them how awful he is to live with and how concerned I am about his behaviour considering his child is there 90% of the time?
I don't care if this is outing
