,1. A user receiving a Canadian record in response to a NCIC wanted person
inquiry is advised in a caveat that the fugitive is wanted on a Canadian
warrant. No arrest can be executed in the United States solely on this
basis.
True (You have to confirm the validity of the record PRIOR to taking any
action)
Rationale: A Canadian warrant does not grant automatic extraterritorial arrest
authority to United States law enforcement officers. Before any detention or
arrest can be executed based on a foreign warrant, the U.S. agency must
formally confirm the validity of the hit with the entering Canadian agency,
establish extradition status, and secure a domestic provisional arrest warrant
through the U.S. Department of Justice if extradition is authorized.
2. When executing a device file status check (a.k.a DFST), DMVOL describes
what file?
Department Of Motor Vehicles, Photo Server
Rationale: Within law enforcement telecommunication switching systems,
device and file status check commands verify the operational availability of
specific external databases. The code DMVOL designates the interface route
connected to the Department of Motor Vehicles' online imaging and photo
retrieval server database.
3. If you inquire on a Texas OLN and your response does not return within a
reasonable amount of time, you should:
Perform a DFST and check the NLETS file status
Rationale: When an out-of-state driver's license inquiry (OLN) stalls, the
operator should execute a Device File Status Check (DFST) to determine if the
connectivity bottleneck is local, systemic to NLETS (National Law Enforcement
Telecommunications System), or isolated to that specific state's regional
interface.
4. All ILLETS inquires must include a completed attention field which must
include:
Any unique identifier
2
, Rationale: System security audits require a completed attention field to tie
every transactional query to a verifiable operator or unit. A unique identifier (such
as a badge number, operator ID, or specific unit descriptor) ensures
accountability and prevents anonymous or unauthorized system usage.
5. All printed information obtained through LLETS that is no longer needed
must be destroyed by tearing or shredding
false (tearing, shredding and burning would be the correct answer)
Rationale: Criminal Justice Information (CJI) security policy mandates
stringent physical destruction parameters for hard-copy data. Tearing alone is
insufficient because the data might still be reassembled; documents must be
completely destroyed via shredding, burning, or pulverizing to prevent
unauthorized data retrieval.
6. Due to variance in state laws and polices, the NCIC III file may not be used
for licensing or non-criminal justice employment purposes by LLETS
agencies
True
Rationale: The NCIC Interstate Identification Index (III) is strictly regulated.
Because non-criminal justice background checks and licensing authorities vary
extensively by state legislation, agencies are restricted from running queries
through III for civilian employment or licensing unless an explicit statutory
exemption exists for that specific purpose code.
7. An NCIC response (a.k.a VIN) alone is probable cause to arrest
Fasle
Rationale: A computer hit response alone does not immediately constitute
absolute probable cause for an arrest. The inquiring officer must first confirm the
status of the record with the entering agency (hit confirmation) to ensure the
record is active, valid, and that the matching individual or vehicle matches the
subject in custody.
