Criminal law:Police suspected that Adam Albert was growing marijuana in his personal residence.Using thermal heat detectors, they were able to detect unusual high levels of indoor temperature.Growing marijuana requires a significant amount of light which generates heat.Based on the findings of the heat detectors, police were able to obtain a search warrant for the residence and found marijuana being grown illegally.

On trial, Adam Albert argued that the use of the heat sensors was an illegal search because it searched the interior of his house which is a protected area.The police argued that they never entered into the home and the heat showing on the exterior of the house should be considered "in plain sight" and not need a search warrant.

Note that the heat patterns in growing marijuana are significantly different than those of individuals who maintain a warmer than usual setting in their home

Should the court consider the existence of the heat "plain sight" or not.
