like someones said the law aint gonna send a chopper for a small grow its like what you see on police cammara action when some one does a runner the chopper can pick up thermol images as it would wouldnt it if someone had a attic bedroom the door could go in your bustedfor been in bed so how would they no, on one hand it could be a grow room on the other its a attick bedroom ive mentioned this to my mate he said you could have the lights on in the daylight hours if it really worried you but why would the chopper be out at night i live by the see so if you do here it its searching the sea once when there was a murder what im saying is theres a good chance you would here it
