The Fourth Amendment in the Twenty-First Century: Technology, Privacy, and Human Emotions

Police and local political officials in Tampa FL argued that the FaceIt system promotes safety, but privacy advocates objected to the city\u27s recording or utilizing facial images without the victims\u27 consent, some staging protests against the FaceIt system. Privacy objects seem to be far more widely shared than this small protest might suggest

What is Probable Cause, and Why Should We Care?: The Costs, Benefits, and Meaning of Individualized Suspicion

Taslitz defines probable cause as having four components: one quantitative, one qualitative, one temporal, and one moral. He focuses on the last of these components. Individualized suspicion, the US Supreme Court has suggested, is perhaps the most important of the four components of probable cause. That is a position with which he heartily agree. The other three components each play only a supporting role. But individualized suspicion is the beating heart that gives probable cause its vitality

Foreword: The Political Geography of Race Data in the Criminal Justice System

Several months ago, there was a heated discussion on CrimProf, the listserv for criminal law professors, about the disproportionate representation of minorities in the criminal justice system. Few participants in this online discussion contested the reality that racial and ethnic minorities, especially African Americans, make up a far larger percentage of those arrested and incarcerated than should be expected from their percentage of the country\u27s total population

A Revised Characterization of the WFPC2 CTE Loss

Charge-transfer loss on the Wide Field Planetary Camera 2 (WFPC2) onboard the Hubble Space Telescope is a primary source of uncertainty in stellar photometry obtained with this camera. This effect, discovered shortly after the camera was installed, has grown over time and can dim stars by several tenths of a magnitude (or even more, in particularly bad cases). The impact of CTE loss on WFPC2 stellar photometry was characterized by several studies between 1998 and 2000, but has received diminished attention since ACS became HST's primary imager. After the failure of ACS in January 2007, WFPC2 once again became the primary imaging instrument onboard HST, restoring the importance of ensuring accurate CTE corrections. This paper re-examines the CTE loss of WFPC2, with three significant changes over previous studies. First, the present study considers calibration data obtained through 2007, thus increasing the confidence in the reliability of the CTE corrections when applied to recent observations. Second, the change in CTE loss during readout is accounted for analytically. Finally, a reanalysis of the CTE dependencies on counts, background, and observation date was made. The resulting correction is significantly more accurate than that provided in the WFPC2 Instrument Handbook (Dolphin 2002 and updates through 2004), resulting in photometry that can be enhanced by over 5% in certain circumstances.Comment: 30 pages, 11 figures.
