D. Spitt<strong>in</strong>g on the SidewalkIn Commonwealth v. Cabral 46 the defendant was suspected of rap<strong>in</strong>g <strong>and</strong> impregnat<strong>in</strong>g a mentally challenged girl whilework<strong>in</strong>g as a tradesman <strong>in</strong> the parent’s home. Based on the tim<strong>in</strong>g of the pregnancy, the defendant was asked toprovide a DNA sample to police. He refused. As there were <strong>in</strong>sufficient grounds to obta<strong>in</strong> a warrant, the family hired aprivate <strong>in</strong>vestigator, on leave from the New Bedford Police Department, to survey Cabral <strong>and</strong> covertly attempt toobta<strong>in</strong> a DNA sample.Work<strong>in</strong>g <strong>in</strong>dependently of the police department, the <strong>in</strong>vestigator devised a plan where<strong>in</strong> his assistant wouldcontact the defendant to arrange for plumb<strong>in</strong>g work at his house. Cabral performed the requested plumb<strong>in</strong>g work,dur<strong>in</strong>g which time he spat on the sidewalk outside the <strong>in</strong>vestigators home. The spittle was collected <strong>in</strong> a napk<strong>in</strong> <strong>and</strong>sent to a forensic laboratory for genetic test<strong>in</strong>g. The results implicated Cabral, were passed on to the police <strong>and</strong> a DNAwarrant confirmed his parentage.At trial the admission of the DNA <strong>evidence</strong> was upheld as the defendant had no expectation of privacy <strong>in</strong> hissaliva when he ab<strong>and</strong>oned it on a public sidewalk. On appeal, Cabral argued that the trial judge erred because theDNA sample was obta<strong>in</strong>ed <strong>in</strong> a ruse devised by a State actor, <strong>and</strong> that his State <strong>and</strong> Federal constitutional rights wereviolated.The Massachusetts Court of Appeal disagreed, hold<strong>in</strong>g that the defendeant lacked any expectation of privacy <strong>in</strong>the spittle that he had ab<strong>and</strong>oned, <strong>and</strong> that the police did not act improperly <strong>in</strong> collect<strong>in</strong>g it.[Although] the defendant had a reasonable expectation of privacy <strong>in</strong> his saliva (<strong>and</strong> other bodily fluids), when he expectorated [spit] on toa public street <strong>and</strong> did not retrieve the fluid, he voluntarily ab<strong>and</strong>oned that protection; he assumed the risk of the public witness<strong>in</strong>g hisaction <strong>and</strong> thereafter tak<strong>in</strong>g possession of his bodily fluids….Thus, where the defendant here voluntarily ab<strong>and</strong>oned his saliva onto apublic street, the <strong>in</strong>vestigator (whether deemed to be function<strong>in</strong>g <strong>in</strong> a private capacity or as a State actor) did not <strong>in</strong>fr<strong>in</strong>ge on anyreasonable expectation of privacy when he recovered the spittle from the street. 47Although not a consideration by the Court, most jurisdictions make it an offence to spit <strong>in</strong> a public place. Suchlaws were passed at the turn of the last century to prevent the spread of diseases such as Tuberculosis. In 1907, forexample, the City of W<strong>in</strong>nipeg passed an anti-spitt<strong>in</strong>g by-law. That by-law rema<strong>in</strong>s <strong>in</strong> force today as part of the Anti-Litter By-law, which makes it an offence to spit <strong>in</strong> a public other than <strong>in</strong> a litter receptacle. 48 The by-law further def<strong>in</strong>esa “public place” as be<strong>in</strong>g “any <strong>and</strong> all streets, sidewalks, boulevards, alleys or other public ways <strong>and</strong> any <strong>and</strong> all publicparks, squares, spaces, grounds <strong>and</strong> build<strong>in</strong>gs which are owned by or under the control <strong>and</strong> jurisdiction of the City”. 49As such the police would be lawfully entitled to collect spit (or cigarette butts, paper cups, straws, etc), not only asab<strong>and</strong>oned or <strong>discarded</strong>, but also as part of their duty to <strong>in</strong>vestigate offences. 50E. A Lick <strong>and</strong> a PromiseOther police agencies have turned to more creative approaches, such as that used by the Seattle Police Department(SPD) to solve the murder of 13-year old Kristen Sumstad <strong>in</strong> 1982. The victim was found stuffed <strong>in</strong> a cardboard box <strong>in</strong>an alley <strong>and</strong> semen was found <strong>in</strong> her vag<strong>in</strong>a <strong>and</strong> on her leg. An autopsy also revealed microscopic hemorrhag<strong>in</strong>g orbruis<strong>in</strong>g to her anus, bruis<strong>in</strong>g <strong>and</strong> contusions on her face, neck, <strong>and</strong> legs, <strong>and</strong> a possible abrasion on her labia,. Allsigns <strong>in</strong>dicated a forced sexual assault.John Athan became a suspect early <strong>in</strong> the case because he had been seen carry<strong>in</strong>g a similar box earlier <strong>in</strong> the day,however police were unable to lay charges due to <strong>in</strong>sufficient <strong>evidence</strong>. In 2002 the case was re-opened <strong>and</strong> a DNAprofile obta<strong>in</strong>ed from the crime scene. Athan now lived <strong>in</strong> New Jersey, <strong>and</strong> had family <strong>in</strong> Greece. The SPD consideredhim a serious flight risk if he were to learn of the re-<strong>in</strong>vestigation, <strong>and</strong> the police had to wait for the results of a DNAwarrant before they could charge him. As a result, the police <strong>in</strong>vented a ruse to obta<strong>in</strong> his DNA without mak<strong>in</strong>g himaware they had resumed <strong>in</strong>vestigat<strong>in</strong>g the murder.Writ<strong>in</strong>g on the stationery of a fictitious law firm, the SPD sent a letter to Athan that asked him to jo<strong>in</strong> a classaction lawsuit to recover overcharged traffic f<strong>in</strong>es. The letterhead conta<strong>in</strong>ed the names of the “attorneys,” all of whomwere employed by the SPD. Believ<strong>in</strong>g the ruse to be true, Athan signed, dated, <strong>and</strong> returned the enclosed class action4647484950Commonwealth v. Cabral (2007), Docket No. 06-P-987 (Mass.
