Now, I could post many more stories highlighting aerial sightings of sunflowers being sworn on an affidavit to be marijuana plants leading to raids, or the many homeowners killed through the police's ridiculous tactics, while all the while tying it to the erosion of the Exclusionary Rule, Qualified Immunity, and the Circular Force Continuum. You may be wondering what my point is. My point is simply that they can get a warrant because of electrical usage abnormalities. The two circumstance test is not required. That does not mean that they will not attempt to make their warrant look stronger than it is (that way if they fuck up, which they know is a very real possibility, they can point to the various things and cower behind their qualified immunity). The officer may cite garbage cans not being put out on trash day, or vehicles coming and going, or a heat signature abnormal to the other homes in the neighborhood, or a skunky smell, or cameras on the outside of the home, the purchase of grow lamps and more. There is a practice of "warrant shopping" that is prevalent as well.
As to why the electric company would wish to inform upon their most valuable customers, I can only assume it is because they, individually, sat through some 17,000 hours of indoctrination, some of which included seminars from DARE officer friendly to turn in their parents, and because they are petty. I really can't rightfully say why some people feel so compelled to call the police. It's a weird, and prevalent, phenomenon. An electric company actively ignoring abnormal electrical patterns would not be above the DOJ's harassment. I'm also not specifically aware of what laws are in place regarding this. It has happened. It will happen again. And if it's your freedom on the line, one would be wise to take heed to the various unconstitutional, criminal tactics that the police are using and the help they are receiving from companies and people in general.
