they use those for spotting indoor crops...they look for a heat signature given off by the high powered lights marijuana growers love to use
I am not sure how well equipped our law enforcement and marijuana eradication powers that be are, but if they are well equipped, they can do just about anything.... believe me. I just go into this whole ordeal realizing that one day if I slip for just a second, the powers that be can get me in a pinch
I also go into this ordeal believing that they allready know what I'm doing and they are watching me....It takes a while too build a case... If you don't look at it in that perspective, you are setting yourself up for failure
but as far as the helis, what they do is look for growers, rat them out to law enforcement, and make a name for themselves.......whatever your laws is in your hood, just make sure you know them well if ....just in case the time ever comes where you slip and get caught....
peace bros!
