Study Notes

Forensic Science Challenges

Numerous issues have surfaced in forensic science disciplines in recent years.
Massachusetts chemist faced charges for “dry-labbing,” compromising data integrity.
North Carolina lab agents were found to have manipulated and withheld results from numerous tests.
Florida's Department of Law Enforcement chemist was arrested for stealing evidence.
The FBI acknowledged overstating the reliability of hair and trace analysis.
An expert witness was accused of falsifying personal credentials.

Legal Landscape of Digital Forensics

Digital forensics operates within an evolving legal framework, particularly regarding password access.
Courts face challenges about compelling individuals to disclose passcodes in legal cases.

Search Warrant Fundamentals

Search warrants authorize law enforcement searches based on probable cause as validated by a judge.
Protects citizens against unlawful search and seizure in accordance with the Fourth Amendment.
Specifies the items to be searched, personnel authorized to conduct the search, and the search location.

Scope of Search Warrant

Items in electronic storage must focus on relevant file content rather than the physical storage devices.
Investigators must adhere strictly to the warrant's scope and may need additional warrants if new evidence emerges.

Execution of Search Warrant

Designates a law enforcement officer or analyst from a crime lab to conduct searches.
Warrant language supports the removal of items for forensic analysis offsite.
Must be executed typically within 10 days, though analysis can take longer, relying on the definition of "reasonable time."

Best Practices in Digital Forensics

Best practices vary based on the specific work environment (e.g., battlefield vs. crime lab).
Standard Operating Procedures (SOPs) should be documented and regularly updated.
A comprehensive Quality Control program ensures consistent standards across practices.
Validation testing is essential for confirming the reliability of forensic tools.

Documentation in Forensics

Thorough documentation is critical; if it's not written down, it is as if it never happened.
Documentation includes all forensic processes and findings to maintain integrity.

Training for Forensic Analysts

A defined training program is necessary, with a qualified trainer overseeing the curriculum.
Training includes forensic science fundamentals, scientific methods, and courtroom testimony preparation.
Ongoing training is crucial for maintaining proficiency amidst evolving technologies.

Examination Environment and Equipment

Exam rooms must provide adequate power, cooling, and contamination controls.
Workstations should have sufficient processing power and ports for necessary tools.
Essential forensic equipment includes cables, write blockers, storage media, and documentation tools.

Preparing for Forensic Analysis

Review any documentation before analysis, such as search warrants and service requests.
Avoid open-ended analysis; focus on purpose-driven searches for illegal or useful evidence.
