You wanna know what i'd do? I'd go and have a "chat" with nextdoor. Then after the "chat" you got nothing to worry about, cos corpses dont report people do they?
Hint: Use a plastic bag over the head when shooting, as this stops alot of the blood spatter.
No growing outside no more either, even if it is legal because, it's NOT legal and you'll still get fucked by the big guns, just cos small time meatwagon pig twats dont care, dont mean it's fine and dandy, if it was, this "blackmail" wouldnt be able to happen.
But yeah, theres no way i'd allow that, i'd despatch the moron who thought he'd give it ago.
And yeah, im serious, i wouldnt allow myself to be blackmailed, lose weed, be threatened etcetc, especially not by nextdoor neighbours. I'd rather risk prison and murder them than me lose everything, it's a dog eat dog world, kill or be killed.
