Bob Rasta is in the business of growing and selling marijuana $($illegally$)$ in his home in lowa. Like any good drug dealer, Bob has all his windows covered in tinfoil so that no one can see in from outside. One fine day, the police were cruising down Bob's street viewing every home with a thermal imaging camera that shows heat waves $($invisible to the naked eye$).$ On seeing massive amounts of heat radiating from Bob's house, they entered the house without permission, found his drugs, and arrested him. Was this a legal search under the $4$ th Amendment?
