If the cops are clued in enough to be looking at your power bill or though your trash your on their radar and its only a matter of time. How easy is it? They got your power bill showing usage, go by your place to check things out and "smell" weed. Hes a cop, try to prove hes lying after the fact, especially if they nail you. Alot of times cops know whats going on but can't do anything cause their hands are tied by their own rules. How frustrating that must be.. And to those growing legally, don't forget its legal on the local state level, above that its still illegal on the federal level. Even the legal growers should be worried at least a little.
