White people are inherently racist. It has been determined by science. Everywhere the white man goes, he leaves behind a trail of tears and destruction. http://qz.com/502019/if-youre-white-science-says-youre-probably-a-racist-now-what/
I am sorry OP, this thread is getting a bit funny with all the responses. Seriously, having a bad neighbor is something that happen anywhere. Just stick a sale sign, and move out.
The first thing I noticed was that you had a half grassed motivation in the first fifteen minutes, as well as clipping. This led me at first to believe it had to be a Houston Texan offensive lineman. But your second clue was the kicker, the initials S.U.V. There is only one offensive lineman in the league with the Initials S.V., and that is Seastian Vollmer, Tackle, New England Patriots. Go figure. He played college football at Houston. So now we have motive, and location. He is the first and only german to ever play in the NFL. So for sure Nazi involvement. This goes back to WWII my friend. It's a ****storm. The rabbit hole goes pretty deep.
people shining flashlights under a car and walking around it could be innocently looking for a cat and trying to coax it out
Or it could be planting a bomb. OP the reason you're neighbors didn't answer the door, could be because their being held held hostage by your psychopathy neighbors(or worse). Call the cops and be careful.
