Editorial: Take care up there

THE IRONY. As I sat here preparing to write this editorial about taking law enforcement data on the cloud, I got an email from a co-worker, inquiring if I’d had any issues with a website we frequently use in our day-to-day business. I checked, and sure enough, I couldn't log in. Something was amiss.

A Dynamic Range for Impression Evidence

Adobe Photoshop has become a ubiquitous part of the law enforcement digital imaging community, and has cemented itself as an essential forensic tool for impression evidence examiners and crime scene technicians. The focus of this article is to demonstrate Adobe Photoshop’s high dynamic range function (Merge to HDR Pro), which uses multi-exposure images to enhance and visualize indented writing. While this paper focuses on questioned document examination, the use of merging multi-exposure images is applicable for all forensic sciences involving impression evidence, especially hard-to-photograph items, such as questioned documents, latent prints, footwear, overall crime scene photographs, and more.

Debunking the 5 Biggest Myths Around Oral Fluid Drug Testing

Recent headlines have been awash with news on THC (tetrahydrocannabinol)breathalyzer concepts—which are used to detect the presence of cannabis or marijuana—exploring their anticipated use for detecting impairment during roadside stops. This isn’t a surprise, given that 30 states, plus the District of Columbia, have legalized marijuana possession to some degree or another. While the technology behind them is feasible, THC breathalyzers must navigate significant hurdles to achieve scientific validation that speaks to their efficacy for this application.

Focus on Evidence Management Needs

Property and evidence management at law enforcement agencies—once a slow, tedious, and inefficient process bogged down by manual record keeping—has been greatly automated. Yet, even with automation, evidence management nationwide remains fragmented. Some agencies do it well while others flounder because they still use outdated methods, have poorly trained staff, or simply have not made evidence management a high priority. Ineffectual evidence management practices may also be tied to the fact that many agencies under-use their evidence software, thus missing key steps and capabilities vital to protecting chain of custody as evidence is received and eventually checked out for processing or presentation in court.

Video Redaction & Presentation Techniques

Until only a few years ago, redaction was only known as the process of obscuring or censoring part of a printed text document for legal or security reasons—for example, the release of sensitive documents by government agencies with parts redacted to protect individuals, or sensitive information. The same legal and security reasons for applying obfuscation now also exist with still images, and video from body-worn cameras, citizen smartphones, or CCTV. Therefore, the need to have the right tools to deliver this redaction in a timely manner has become critical to the successful adoption of new digital technologies within law enforcement and criminal justice in order to deliver digital evidence.
