Buy a tin of paint (cash) and not locally. Get an old oil can or similar. Wear gloves or avoid leaving fingerprints on the handles - do not wipe it as it'll be a bit suspect that there are none on at all. Get home and empty the paint can contents into another receptical.
Smear some paint on the underside of the paint tins handle. Put the empty paint tin on top of the oil can (so he picks the painted one up first) on his wheelie bin. He will pick them up and drop them in the bin - he'll get paint on his hands and hopefully transfer it (and his prints) onto the other tin, bin, door handle etc. Retrieve the tins from the bin being careful not to smudge his prints on the handles. Fill the oil can with petrol from your car or get someone to fill one of thse red ones for you - dont you go for it.
Go round town with the paint you took out earlier and daub racial, homophobic and anti Police statements around town - on walls, on police cars, the Town Hall etc. Paint something along the lines of 'I'm going to burn you fuckers to death' on the local primary school. Go back to his house and drop the paint can back into the bin - this way you made sure the bin wasn't emptied whilst you went round town. Put the full petrol canister nearby - a shed or behind the bin - somewhere it'd be easily spotted though.
Phone the Police anonymously saying that you overheard a neighbour bragging about his painting antics and how he said he'd got some petrol and was going to set fire to the local primary school when it was full of kids. Give them his name and address.
Sit back and enjoy.
