Kyllo v. US, where the court held that the use of infrared sensors to detect heat emissions from a grow lamp was an impermissible violation of the Fourth Amendment.
Ok heres the scoop on getting busted by electric consumption.
If you live in a big city chances are you are on the grid system. They don't send the electric police out to get you, but instead they can and will follow the electricity you are using. They can follow the juice all the way to the source--->Your grow room. The only time they will do this is when you go over their peak consumption.
Example:
A friend of a friend who is in a rock band has all his equipment at his home, amps guitars and so forth. They rock out everyday and they consume huge amounts of electricity.
Ok so heres the deal. They get a knock on the door one day and to his suprise it's the police along with a rep. from the electric company. They ask him why he is using a lot of electricity, so he explains about all the equipment their band uses. Of course you know they didn't believe that story, so they asked to enter the home to take a look around. Of course he had nothing to hide, so he let them enter.
The first thing they do is head right to the room that has been using all the electricity. Unknown to him, they already knew exactly which room it was. After looking in that room they decided to ask if they could look around the rest of the place, which he said ok.
After looking through the whole place and not finding any marijuana plants, the police start to give him probs. saying they know he is growing and to tell them where it's at. Talk about freaking this dude out. He never grew marijuana in his entire life, and he kept telling them that they are out of their minds.
So after giving him probs. they left, but not for long. About two hours later they were back and they brought a technician with them who worked for the electric company. They asked him to power up all his equipment so that they could get a reading from it to see if his equipment really was the source. Turns out it was the source of the electric consumption. After talking with the tech. he discovered he was on a grid system and they knew the whole time which room was using up the electricity.
So beware if your on a grid system. To find out if you are, just call your electric company they will tell you all you need to know, including how much consumption triggers a red flag.
Thank God I use solar & wind power to offset my electric consumtion. But then again I'm not on a grid system so It really doesn't matter.
Hope this made since! Didn't to me, but it's a true story!
