| Motion to Exclude DNA Testimony About Likelihood Ratios Obtained Using STRMix Probabilistic Genotyping Software | This motion relies on the Federal Rules of Evidence to argue for exclusion of expert DNA testimony about the likelihood ratio obtained using STRMix probabilistic genotyping software. Pages 5-8 describe the basic steps of DNA extraction and analysis. Pages 8-9 discuss the problems of trace DNA and the possibility of innocent transfer of DNA. Page 11 explains how DNA analysis is less reliable when there is a complex DNA mixture and pages 12-15 discuss the danger that jurors will misunderstand (and prosecutors will misrepresent) what a likelihood ratio actually means. | May 20, 2024 | National, Washington | 403, DNA, DNA Mixture, Evidence, Expert Testimony, Forensics, Improper Argument by Prosecutor, Juries, Juror Psychology, Likelihood Ratio, Secondary Transfer, Witnesses | national washington | 403 dna dna-mixture evidence expert-testimony forensics improper-argument-by-prosecutor juries juror-psychology likelihood-ratio secondary-transfer witnesses | |
| Expert Reports on Low Rates of Sex Offense Recidivism and the Counterproductive Impact of Sex Offender Registration and Notification (SORN) Requirements on Public Safety, Deterrence, and Recidivism | The ACLU of Michigan included these reports as exhibits in its recent litigation attacking the constitutionality of Michigan’s Sex Offenders Registration Act (SORA). Does v. Whitmer (Does III), No. 22-cv-10209 (E.D. Mich.). The research cited in these reports — specifically on the low risk of recidivism among people convicted of sexual offenses and the counterproductive impact of registration/notification requirements on public safety and recidivism — could be used (1) when negotiating with a prosecutor for a plea to a non-registration offense, (2) when justifying such a plea to a sentencing judge, (3) in pre-trial release arguments, (4) in sentencing arguments where clients will be forced to register to show the onerous nature of registration, or (5) to support a motion in limine to preclude reference to a client as a “sex offender.” (Note that the following page numbers are keyed to the page numbers in each expert report, which you can find in the middle bottom footer of each report): Letourneau Report Pages 2-11: Explaining through a dozen different scientific studies that sex offender registration and notification laws fail to increase community safety, do not have a general deterrent effect, and may even increase the incidence of crime by making it difficult for ex-offenders to find and maintain housing, employment, and social relationships. Pages 11-12: Noting that researchers have found no connection between juvenile registration/notification and an increase in public safety but they have found increased incidences of attempted suicide among juvenile registrants as well as an increase in their likelihood of being victims of sexual assault themselves. Pages 12-13: Citing research showing that 80% to 90% of adult males convicted of sex offenses are never reconvicted of a new sexual crime, including studies that debunk recidivism myths by showing rates of recidivism as low as 2-5%. Pages 13-14: Discussing research showing that conviction offense has no bearing on recidivism risk. Pages 16-17: Citing research showing the negative impact of registration on people’s mental health and ability to find and maintain stable housing, employment, and prosocial relationships, creating barriers for reintegration. Pages 17-20: Discussing why the costs of implementing sex offender registration and notification laws are greater than any savings or benefits generated by those laws Pages 21-22: Finding no correlation between failure-to-register violations and sexual recidivism Socia Report Pages 4-8: Citing research showing that 90-95% of all sex crime arrests are for first-time offenders; the vast majority of sex crimes are not committed by strangers; and sex offender registration and notification laws do not reduce recidivism or make communities safer Page 9-12: Debunking through scientific research any suggestion that there is a high sexual recidivism rate and noting that sexual recidivism rates are actually lower than those of any other offense except murder Pages 16-17: Noting that language matters to public perceptions and that individuals are more likely to think negatively about someone described as a “sex offender” than someone described as an “individual convicted of crimes of a sexual nature” (this research might support a motion in limine about how clients should be described in court) Pages 19-22: Documenting how individuals on the sex offender registry are stigmatized in ways that affect reintegration including compromising employment and housing opportunities, as well as social support networks Pages 22-25: Noting that there is no consistent evidence that failure-to-register convictions predict increased sexual recidivism. | October 2, 2023 | National | 403, Character Evidence, Evidence, Expert Testimony, Improper Argument by Prosecutor, Juries, Juror Psychology, Pre-Trial Release, Sentencing, Sex Offender Registration, Witnesses | national | 403 character-evidence evidence expert-testimony improper-argument-by-prosecutor juries juror-psychology pre-trial-release sentencing sex-offender-registration witnesses | |
| Amicus brief argues in a family defense case that courts should not equate parental substance use with “substance abuse” absent a clinical diagnosis of a Substance Use Disorder (SUD) consistent with the DSM-5-TR | This brief argues that, contrary to stereotypes, drug use alone—even frequent or illicit use—does not necessarily indicate substance abuse (pp. 23, 28-29). Only a minority of users develop a diagnosable SUD (p. 23). A single positive drug test is insufficient to establish a SUD (p. 29). And equating substance use, even a SUD, with substantial risk of harm to a child is unsupported by the medical evidence (pp. 40-42). Defenders can use the research collected in this brief to file motions in limine to exclude evidence of or arguments about substance use as more prejudicial than probative or to obtain expert testimony on substance use. The research could also be useful at the pretrial release and sentencing stages to suggest that clients do not suffer from a substance abuse disorder and do not pose a danger. | April 4, 2023 | California, National | 403, Evidence, Expert Testimony, Improper Argument by Prosecutor, Pre-Trial Release, Probation, Sentencing, Substance Use, Witnesses | california national | 403 evidence expert-testimony improper-argument-by-prosecutor pre-trial-release probation sentencing substance-use witnesses | |
| Brief – Impact of Prosecutor’s Racially Charged Language | p. 30 – 37 discuss studies of implicit bias and the ways that racial cues – like a prosecutor characterizing a Black man as ‘angry’ – can “automatically affect a broad range of decisions and behaviors” within juries. | June 4, 2021 | Massachusetts, National | Improper Argument by Prosecutor, Juries, Juror Psychology, Race | massachusetts national | improper-argument-by-prosecutor juries juror-psychology race |
