Ballistics evidence records

Identifies documents containing references to ballistics evidence records in international contexts. This information type is classified as personally identifiable information under applicable data protection regulations. Coverage differentiates forensic ballistics records and findings from education and general firearms discussion; generic firearms-analysis language is discovery-only unless independent forensic case or examination-result evidence is present.

Should not match

unrelated generic text without domain phrases — No relevant topic phrases present
placeholder value 12345 — Random text should not match topic-specific regex
mugshot victim — Generic word pair from old broad template should not match
The university course introduces firearms analysis methods. — Educational firearms-analysis prose is demoted — discovery only, must not enforce
Training exercise: exhibit E-00 is a fictional shell casing used for examiner practice. — Training-exercise exclusion suppresses the shell-casing anchor
firearms analysis — Bare contextual phrase — discovery only, must not enforce

Known false positives

Common words and phrases related to ballistics evidence records appearing in policy documents, training materials, HR templates, or compliance guidelines without actual personal data. Mitigation: Require corroborative evidence keywords within the proximity window to confirm sensitive data context rather than general discussion.
In English (as the primary international business language), similar terminology used in formal or administrative contexts (education, professional documentation) that does not constitute sensitive data collection. Mitigation: Layer with additional contextual signals such as structured identifiers, form fields, or database column headers to distinguish sensitive records from general references.
High-frequency pattern matches in large document corpora due to broad regex anchors. Expected match rate is significantly higher than specific identifier patterns. Mitigation: Tune confidence thresholds for bulk scanning. Consider using this pattern primarily as a pre-filter with secondary validation.
