Nope. This sounds like clearly overstepping bounds of 4th amendment, although I totally agree that there has been tremendous erosion, especially since the towers came down. However, a few years ago, I forget the jurisdiction, but the police used an infrared scanner to "see" how much light/heat was coming out of a house, and if it was too much(?) they raided the place, expecting to find a grow operation. S. Ct said that wasn't enough. And just recently there was decision that does not allow drug dogs to sniff around your curtilage without probable cause. So take heart, there are still some limits. I joke with the local constabulary here. It's a small town and they all know I grow flowers, because I have participated in the local flower shows. Otherwise, I am afraid that they would be here every whip stitch. Meanwhile, know that your electric bill is subject to scrutiny, because its a business record and not strictly yours.
