lip sometimes you just rabbit on .for a start the copper chopper cant see into your loft the can only trace surface heat so if its hot out then they can see nothing and if your lights are on at night they will show no more heat than attic thats been converted to a bed room and they couldnt get a warrent through that evidence alone i live in a high crime area and the copper chopper is over head all the time.Actually once they were chasing car theifs and hovered over my house one night with the infrared heat seek on searching for this dude and my lights were on full and i operate 1x1000watt hps 1x 1000 watt mh 4x 85 watt fluros and 3x 100 watt cfls and nothing this heat seekin shit is a myth people seem to think it can see the heat seeker can see in your property it doesnt it can only see surface heat and if your attic is insulated it will se shit .I think you are relying on the time your little brother got caught with the chopper copper on tv.the postman.
