Predictive Tip Supports Terry Stop
An anonymous caller told officers that Idina Iverson would exit a downtown co-working space at 8 p.m., drive her blue hatchback two blocks east, and meet a contact in a parking garage to exchange stolen source code. Officers observed Iverson follow the exact sequence of movements. The corroborated predictions supplied sufficient indicia of reliability to justify the stop.
Bare Description Yields No Suspicion
An anonymous caller reported that Ismael Ibrahim, wearing a white linen shirt and standing by a hotel fountain with two rolling suitcases, was transporting illegal firearms. Officers confirmed only the visible description and location before frisking him. The absence of predictive information or other indicia of reliability meant the tip could not justify the stop and frisk.
Ines Ibarra offered a computer scientist to testify that a rival algorithm did not infringe a patent, relying on a self-developed benchmarking script. The court conducted a Daubert hearing and considered whether the script had been tested, peer-reviewed, or shown to have a known error rate. The flexible approach permitted the court to weigh these indicia of reliability for technical expertise.
Expert Data Supports Clinic Ruling
Israel Irving, an expert witness, presented research tracking the number of open abortion clinics and projected patient volume increases after new facility requirements took effect. The district court credited the testimony after finding indicia of reliability in the underlying data collection methods and participation of university researchers. The findings supported the conclusion that the requirements would impose an undue burden.
Whole Woman’s Health v. Hellerstedt579 U.S. 582 (2016)
In July 2013 the Texas Legislature enacted House Bill 2.
The bill contained an admitting-privileges requirement for physicians performing abortions and a surgical-center requirement for abortion facilities.
Before the law took effect a group of Texas abortion providers filed the Abbott case seeking facial invalidation of the admitting-privileges provision. The district court initially enjoined the provision but the Fifth Circuit vacated the injunction and later upheld the requirement on the basis of evidence presented before enforcement.
On April 6 2014 petitioners a group of abortion providers that included some Abbott plaintiffs filed this suit in federal district court. They sought as-applied relief against the admitting-privileges requirement for facilities in McAllen and El Paso and a statewide injunction against the surgical-center requirement claiming violations of the Fourteenth Amendment.
The district court held a four-day bench trial and received stipulations expert depositions and testimony. It found that the number of facilities providing abortions dropped in half from about 40 to about 20 after the admitting-privileges requirement began to be enforced. It found that the number of women of reproductive age living more than 50 miles from a clinic doubled. The number living more than 100 miles away increased by 150 percent. The number living more than 150 miles away increased by more than 350 percent. The number living more than 200 miles away increased by about 2,800 percent.
It found that the number of facilities would drop to seven or eight if the surgical-center provision took effect. It found that before H. B. 2's passage abortion was an extremely safe procedure with very low rates of complications and virtually no deaths. It found that abortion was safer than many more common procedures not subject to the same level of regulation. It found that the cost of compliance with the surgical-center requirement would most likely exceed 1.5 million dollars to 3 million dollars per clinic.
On the basis of these findings the district court enjoined enforcement of both provisions. The Fifth Circuit reversed in significant part holding that res judicata barred the challenges and that both requirements were constitutional. The case reached the Supreme Court.
Iain Irons, who suffered from severe mental illness, walked into a police station and confessed to a homicide. No physical evidence or independent witnesses linked him to the crime. The absence of substantial indicia of reliability extrinsic to the confession itself prevented its admission under due process standards.
Colorado v. Connelly479 U.S. 157, 169-70, 107 S.Ct. 515, 523, 93 L.Ed.2d 473, 486 (1986)
Respondent Francis Connelly approached Officer Patrick Anderson of the Denver Police Department on August 18, 1983, at approximately 2:40 p.m. and stated that he had killed someone and wanted to talk about it. Anderson immediately advised respondent of his Miranda rights. Respondent stated that he understood those rights but wanted to talk about the murder anyway.
At this point, respondent stated that he had come all the way from Boston to confess to the murder of Mary Ann Junta, a young girl whom he had killed in Denver sometime during the month of November 1982. Respondent was then taken to police headquarters. A detective again advised him of his rights. After respondent answered that he understood them, he was asked to describe the murder in detail.
Respondent gave a lengthy account including the location of the body, the date of the murder, the fact that he had used a blunt instrument in the killing, and that after killing the victim he had washed his knife in a nearby stream. After hearing this account, the detective arrested respondent for the murder of Mary Ann Junta. A search of the area where respondent said the body was located revealed the body of a young girl. The cause of death was determined to be a skull fracture.
At a preliminary hearing, the psychiatrist who had examined respondent testified that at the time of the confession, respondent was clearly suffering from chronic schizophrenia and was in a psychotic state at least as of the time of his arrest. The psychiatrist testified that respondent's psychosis motivated his confession, that respondent was not capable of making a free and intelligent decision to confess, and that the confession was not voluntary. The trial court found that respondent's initial statement to Officer Anderson was involuntary and ordered that it be suppressed. The trial court also ruled that the subsequent statements made at the police station were tainted by the prior involuntary statement and ordered that they too be suppressed. The Colorado Supreme Court affirmed the suppression order.
The United States Supreme Court granted certiorari to decide whether respondent's confession was obtained in a manner that violated the Due Process Clause.
Isabella Ingram offered expert testimony that a medication caused birth defects, relying on animal studies and reanalysis of existing data. The court assessed whether the methodology had been tested, subjected to peer review, and generally accepted in the scientific community. These indicia of reliability determined whether the testimony could reach the jury.
Daubert v. Merrell Dow Pharmaceuticals, Inc.509 U.S. 579, 592 (1993)
Two minors brought suit against Merrell Dow Pharmaceuticals, claiming they suffered limb reduction birth defects because their mothers had taken Bendectin, a drug prescribed for morning sickness to about 17.5 million pregnant women in the United States between 1957 and 1982.
Limb reduction defects occur in fewer than one birth out of every 1000. Scientists do not know the mechanism by which any teratogen causes such defects. The plaintiffs offered testimony from three groups of experts. One group proposed to testify to a statistical link between Bendectin ingestion during pregnancy and limb reduction defects based on reanalyses of published studies that had reported no such association. A second group proposed to testify that Bendectin causes limb reduction defects in humans because it causes such defects in laboratory animals. A third group proposed to testify based on the similarity of Bendectin's chemical structure to other drugs suspected of causing birth defects.
The district court granted summary judgment to Merrell Dow after excluding the plaintiffs' expert testimony. The Ninth Circuit affirmed that decision. The Supreme Court granted certiorari, reversed, and remanded for consideration under Federal Rule of Evidence 702.
On remand, the Ninth Circuit examined the affidavits and prior trial testimony of the plaintiffs' experts. None of the experts had studied the effect of Bendectin on limb reduction defects before being hired to testify in this or related cases. None had published his work on Bendectin in a scientific journal. The only review their work had received was by judges and juries.
Plaintiffs' epidemiological experts made vague assertions of a statistically significant relationship between Bendectin and birth defects but did not state that the relative risk exceeded two. With the exception of Dr. Palmer, the remaining experts were willing to testify only that Bendectin is capable of causing birth defects. Dr. Palmer alone was willing to testify that Bendectin did cause the limb defects in each of the children, based on his review of the plaintiffs' medical records and his conclusion that Bendectin is a teratogen.
What makes an anonymous tip sufficiently reliable for a Terry stop?
An anonymous tip carries sufficient indicia of reliability when it accurately predicts the suspect's future movements or conduct that officers can corroborate in real time. Such predictions suggest the tipster possesses inside knowledge of criminal activity rather than merely describing observable facts.
Supporting sources
When does a tip fail to supply reasonable suspicion?
A tip fails when it merely describes a person's visible characteristics and location without predictive information or other indicia demonstrating inside knowledge. Officers who corroborate only innocent details obtain no basis for a stop or frisk.

How do courts assess reliability of non-scientific expert testimony?
Courts apply a flexible, case-specific inquiry and may consider the Daubert factors or any other appropriate indicia of reliability suited to technical or specialized fields. The gatekeeping function requires evaluating whether the principles and methods are reliable and reliably applied to the facts.
Supporting sources
What role do indicia of reliability play in due-process analysis of confessions?
Due process requires substantial indicia of reliability, based on evidence extrinsic to the confession itself, before admitting a confession from a mentally ill person. A bare confession lacking such external markers cannot support conviction.
