How much evidence is needed for the police to raid a home?

Clark has it right. If they can convince a judge of probable cause they can get the warrant. Many thing might be used for that, i.e. witnesses, evidence found at the scene of the graffiti, your connection with the graffiti subject your brags about it on Facebook, etc. .The warrant will describe specific things they are looking for like paint, paint cans, brushes, traces of paint on clothing that can be traced to you, paint on your person, your fingerprints on the spray cans, or in the case of one idiot I heard of, all of the above and pictures of his work all over his walls.
