Katz is out of the Bag:
Katz�s Weaknesses & the Rapidly Emerging Technology of Today and the Future.�

c.�������� Pre-Katz Analysis
����������� Under a pre-Katz property based law evaluation, the result changes completely, focusing on a trespass into the vehicle rather than a sampling of the driver�s breath.� The Sniffer samples air from the inside of the car, using its pump to suck the air out.� The car would be considered private property, and could not be searched in anyway without a warrant.� Recall Silverman, where the court held officers actions constituted a search when a microphone was merely placed inside of the heating duct. � This minute trespass is similar to the Sniffer using the air intake pump to pull air out of the car and evaluate it.� Because the Sniffer would constitute a physical search of the vehicle and not just the driver�s breath, law enforcement could not use the Sniffer without a warrant.
5.�������� Mass Spectrometry and Gas Chromatography
a.����������� Traditional Katz Analysis
����������� When applied to drug detection, mass spectrometry and gas chromatography are a unique combination of the Sniffer and a drug detecting dog.� These molecule detection units detect drugs by sampling the air around a person or package.� Proponents of the molecule detector hail the device as being far superior to drug sniffing canines. � The technology is passive, meaning it is likely to receive the same analysis as drug sniffing dogs in Caballes.� Only two cases have been heard involving similar devices, although neither was discussed in any depth. � Individuals possessing narcotics could demonstrate a subjective expectation of privacy any number of ways.� This paper will assume a subjective expectation of privacy has been asserted, in order to move on to the objective prong of Katz.
����������� Under a traditional objective Katz inquiry, molecule detectors would not constitute a search.� Much like dog sniffs; the molecule detector is capable of detecting only drugs.� No other personal information is acquired, and the detector itself may be used a short distance from the suspect or a package, without intrusion.��� An individual has no right to possess contraband; therefore, society would not consider the molecule detector to invade any reasonable expectations of privacy.
b.�������� Neo-Katz Analysis
By focusing on �how the molecule detector reveals information,� it becomes clear that society has a reasonable expectation of privacy from the detector�s intrusion.�� The molecule detector screens the air through a tube that is capable of detecting even the smallest amount of drugs.� Molecules can be identified as small as one part per one hundred trillion. � To work, the device need only screen air surrounding a person or object.� For the purpose of this section, the paper will assume that the individual is not in a vehicle, as that discussion would be identical to the analysis of the Sniffer.� Instead, focus will be on a person on the street, or a package in the possession of that person.� Because the molecule detector can detect contraband without intrusion, and without revealing any intimate details about the person, it would seem to pass a neo-Katz test as well.� Only after close scrutiny of the detector�s reliability do the privacy implications become apparent.��
The molecule detector is too reliable for its own good, resulting in too many positive readings.� The detectors are boasted to have a 99% reliability rate; that is, 99% of the time, the substance the detector is alerting to is actually contraband. � The problem is that the molecule detector is too sensitive, giving off false positives when the suspect actually has no contraband on him.� Consider the following examples.� A woman walks into her office the first day of work.� She shakes hands with over fifty people.� On her lunch break, she takes the subway, touching doors and turnstiles, and handles two newspapers left on the seats.� On her way back to work, officers armed with a molecule detector receive a positive signal emanating from the woman�s hands.� Next, consider a banker, handling money all day long.� In each hypothetical, the individual is exposed to public areas where molecules from contraband could easily be picked up.� It is no secret that there is a small amount of cocaine on currency. � Although in trace amounts, an unsuspecting handler would be tainted with enough molecules to be detected, even after washing her hands. � Trace amounts of contraband could be passed hand to hand, or by touching public doors and railings.� These molecules may not be deposited into public by only criminals; molecular drug residue could be left by policemen, lab technicians, or bankers.� Due to the oversensitivity of molecule detection units, society would deem it unreasonable to permit intrusion into so many peoples� expectation of privacy.��
c.�������� Pre-Katz Analysis
Under the property based pre-Katz law, there would be no search because the molecule detector can detect contraband without physical trespass.� Contrary to what we have seen so far with emerging technologies and property based Fourth Amendment law, here the public is not afforded greater privacy rights.� This is due to the unobtrusive manner in which the molecule detector operates.� The molecule detector sends no waves or rays into an item.� By sampling air outside of the individual or a package, physical trespass is unnecessary for the detection of contraband.

Each dog requires its own personal operator, who must train it for a year.� Dogs will not work with anyone else, so, if the dog or trainer catches a cold, the team doesn't work. They can only work 15-20 minutes at a time, and no more than 1-2 hours per day.� Dogs require "refresher training" every week.� In addition, Dogs are large, noisy, require large spaces for exercise, produce copious amounts of waste, and are expensive to acquire, breed, train and keep.
