SUBJECT: NIXLE Messages – use and distribution of
PURPOSE: The Rohnert Park Department of Public Safety prioritizes partnerships with
the community and seeks to find innovative ways to distribute information to the public.
Nixle is a networking site in which interested or designated community members can
obtain information from the Rohnert Park Department of Public Safety. This system will
allow community members to better protect themselves or provide information to the
Public to allow for the apprehension of suspects, locate involved vehicles, or otherwise
resolve incidents as well as be advised of events and impactful incidents.
I. BACKGROUND: Nixle is a privately funded company that provides Community
Information Service built exclusively for secure and reliable communications.
The Nixle service is built on an authenticated, secure, reliable, and high-
speed platform; ensuring communications are trusted and accurate.
Nixle currently delivers information to consumers over their cell phones (SMS
text messaging), emails (computers and smart phone devices), and simple
web access at www.nixle.com. Interested citizens can subscribe by area and
choose the level of notifications they desire. Rohnert Park Department of
Public Safety will provide specified information via Nixle to those citizens
who have voluntarily subscribed. Citizens can change their notifications or
unsubscribe at any time. At this time the service is free of charge to the
citizen and the agency.
Nixle is a partner with the National Law Enforcement Telecommunications
System (NLETS). NLETS is a computer-based message switching system that
links together local, state, and federal law enforcement and justice agencies
for the purpose of exchanging information. Nixle’s servers are housed within
the NLETS secured facility. All local, state, and federal law enforcement
agencies can send out instant, geographically-targeted information from
their existing secured law enforcement terminals.
II. POLICY: This policy specifies the manner in which Nixle broadcasts will be
distributed. All personnel using the Nixle networking system will comply with
the current SOP.
III. PROCEDURE:
The following message types are explained to assist you in determining the type of
message to be sent. Command Staff, Sergeants, Detectives and Dispatch personnel
are the current users of the Agency Nixle account. Additional users can be added as
needed.
Alert Messages: Nixle Definition -- Alert messages should be reserved for critically
important information where loss of life and/or property is potentially imminent.
Alert messages are time-sensitive and require your residents to take immediate
action.
RPDPS Example - Includes public warnings and instructions during emergencies;
such as a major earthquake, severe weather alerts, gas leak, or when assistance is
needed with locating an at risk missing person
Advisory Messages: Nixle Definition -- Advisory messages are intended to
communicate important, need-to-know information. Advisories should be
considered less time-critical than Alerts and require a heightened sense of
awareness from your residents.
RPDPS Example -- Includes information about incidents that will impact the
community – such as: police activity or wanted suspects, weather/flooding issues,
minor earthquakes, power outages, traffic congestion, road closures/road work,
etc. Advisory messages can be sent at the discretion of the employee, unless
specific suspect or incident information would require a supervisor’s approval.
Community Messages: Nixle Definition -- Community messages should be used to
convey every day local news, happenings, and developments. Community
messages should not contain any time-critical information.
RPDPS Example -- Includes information to assist the public such as DUI
checkpoints, traffic or special enforcement operations, Crime Prevention Tips,
Community Updates, Town Hall Meetings, National Night Out, POA Santa Sleigh,
employment opportunities etc. Press Releases should also be sent under
Community. Only City or Agency sanctioned events will be sent. Community
messages can be sent at the discretion of the employee.
1. When considering sending an Alert, Advisory or Community message,
the employee should first make sure it has not been sent previously,
or determine if the message is suitable for rebroadcast.
The employee can check to see if a message has already been
broadcast via Nixle by logging into their agency account and
reviewing the “Recent Activity.” If the message is not listed there, it
should be sent out or scheduled to be sent out. Once this is done, the
employee should send a message to the email group “1 Dispatchers”
that the message has been broadcast via Nixle.
NOTE: Press releases should not be attached as PDF files to the Nixle
message. This creates too many links for a user to follow. If the
employee is unable to cut-and-paste from the Press Release PDF and
it’s too long to re-enter, then a MS Word version may be requested
from the original author.
2. Advisory broadcasts involving criminal activity and/or suspects at
large should only be distributed at the direction of a supervisor.
Nixle broadcasts may be done on the following types of cases, or if
otherwise determined by a supervisor, when there is sufficient
information for a BOLO and is suitable for the general public. Some
examples of when a Nixle message can go out:
187 PC, 207 PC, 211 PC, 215 PC
Prowlers, Missing Persons at Risk, Amber, Silver or Blue Alerts.
If appropriate, check the “Request Tip” box on the Nixle message.
3. Nixle Messages shall not include the following information in the
broadcasts, unless approved by the watch commander or supervisor.
• Names of Victims
• Information which indicates a person is 5150 W&I
• Any CLETS/DMV information including registered owner’s
information.
• Any Criminal History or CII and/or III information.
• Address location of private residences (use generic
information i.e. 7300 Block of Adrian Dr)
Broadcasts may contain the following information if applicable;
• Names of Missing adults or juveniles – At risk by
circumstances.
• Suspect name and description
• Business names and addresses are permissible eg. Chevron or
4990 Commerce Bl.
• Vehicle descriptions including license plate numbers.
• Contact telephone numbers for dispatch, investigating
officers/detectives, or watch commander.
• DMV photo of missing or wanted person if available
4. Upon distribution of a Nixle broadcast, the Dispatcher will note in the
remarks of the CAD event that a Nixle broadcast was distributed with
the ID number of the broadcasting employee, if related to an active
CAD event
5. All Nixle messages should have the “Facebook” box checked to
forward the Nixle message to the Department’s Facebook feed. (It is
not necessary to check the “twitter” checkbox because the Facebook
feed is automatically forwarded to the Department’s twitter feed.)
6. Advisory and Community messages can be distributed at the
discretion of authorized Nixle users within the agency. Each discipline
will be responsible for their Nixle messages. For example: Traffic will
send their Checkpoint messages, unless otherwise arranged with
Dispatch.
7. The time of day and the seriousness of the event will be considered prior to
sending Nixle messages. Every effort will be made to ensure messages are
sent out in a timely manner based on the event being broadcast: however,
non-urgent messages should be sent during commute, business or evening
hours. Press releases received after hours should be scheduled for broadcast
by Nixle between 0800-2000 hrs daily, by the dispatcher on duty at the time
of release.
8. When possible, messages should be reviewed by another person prior to
disseminating to avoid sending messages with mistakes or typos.
9. Retention/cancellation of messages: all “BOLO” messages should be
cancelled once resolved. Advisory and Community messages should be set
for cancellation after the situation is over (construction end date, event date
etc.) or self-cancelling in 24 hours, whichever is appropriate.
10. Anonymous Tips
• It is now possible to receive anonymous tips from subscribers if the
message is sent with Tipping enabled. This allows for a user to reply
back via text message information they may have regarding a Nixle
message.
• Nixle Administrators, the Detective and Traffic Sergeants and
Dispatchers are set up to receive the tips via email.
• Upon receipt of a tip, on duty dispatch staff shall respond to the
tipster with acknowledgment that the tip was received and ascertain
if the tip is related to an agency case. The dispatcher should attempt
to ascertain any further information if needed.
• The tip should then be forwarded to the officer or detective
investigating the case. If it is of an urgent nature, it should be
brought to the shift sergeant for follow up.
