Thermal imaging is measuring heat on the property. A geiger counter would be measuring molcules off the property.
I know. all I am saying is, if the decision in post 88 is broad enough - it would say that any detection that can determine the contents of a home, is a warrantless search. this apparantly would also mean that if the police smell or hear something outside a home - that somehow that is a "search" of that home? if the police smell certain meth lab chemicals outside a home, does that consitute a warrantless search?
