Shotspotter - Now you see it, now you don't

By Jill Paperno
Second Assistant Monroe County Public Defender

The NSA is not the only organization that monitors the day to day activities of citizens.  But you already knew that.  One piece of technology that has sprouted up in our own backyard – the city of Rochester – in the last couple of years is called “Shotspotter.”  The company that created this device refers to it as a “gunshot detection system.”

The Shotspotter technology uses sound sensitive devices placed around the city to detect, record and alert to gunshot sounds.  Shotspotter was created and is run by a company in California.  The website is

Although Shotspotter is a fascinating technology, be careful before you depend on getting it in at trial.  Conversely, don't let the DAs get it in without a fight if it hurts your case.

Shotspotter technology produces audiorecordings of the alleged shots, reports of the exact times of each shot, and maps that triangulate to within feet of where the shots were supposedly fired.  In a recent case I tried (and lost) I obtained the records relating to gunshots fired in the area at the time of the shooting through use of a non-judicial subpoena duces tecum.  (The company is not a governmental agency.)  Subpoena service was accepted via internet, though the snafu that occurred initially should have sent off alarms (or shotspotter signals) in my head.

After initially being told service would be accepted, I forwarded a subpoena to the company.  After months without response, but still months from trial, I contacted the company and was emailed the package, including the recording of the gunshots.  The documents and files forwarded included a satellite type map with locations from which the shots were allegedly fired determined through triangulation (within feet), a recording of the gunshots, and the times of the shots.  What was not included was sufficient certification for admissibility, or accurate information about who to contact to get the evidence in at trial.

Prior to trial the contact I had made at the company, Ric Smith, informed me that Shotspotter did not own the technology or maintain the reports for Rochester and could not lay a foundation for the admissibility of the recordings and reports at trial – the City of Rochester owned it and had the records.  I’m still not clear on whether this was accurate for the time of the shooting in my case since we couldn’t ever get a straight answer.  So we subpoenaed someone at the Office of Emergency Communications (as we were initially informed) who represented that he could lay the foundation, and had in the past.  However, soon he developed amnesia, forgetting he had represented that and claiming he could not lay the foundation.  And yes, the prosecution had been in touch with him before he was stricken with this unfortunate illness.  No worries – we were told that members of Rochester Police Department could lay the foundation.  Wrong again – as we were now in trial and contacting the city attorney’s office and RPD, we came up against one obstacle after another.  Eventually RPD sent someone to respond to the subpoena with a single page less professional appearing report that was not the Shotspotter report we had – and reflected fewer shots!!!!

The prosecutors must have known our efforts would fail, as they represented the number of shots throughout trial as half that reflected by Shotspotter, apparently without fear that the documents would be admitted.  (The number of shots might have established the difference between a shootout and what they described as an execution.)

My understanding of how the system presently works in Rochester (and this may differ from the past)  is that the sounds activate a signal in California headquarters, and the information is relayed to RPD.

According to the website, “The instant a shot is fired, gunfire analysis experts at the SST Operations Center review and qualify all alerts  Within seconds SST delivers those qualified alerts to dispatchers, PSAPs and mobile personnel, enhancing the accuracy and speed of response and increasing the usefulness of the system’s database of incidents for pattern analysis.”

What I was ultimately told after a lot of misdirection by RPD and non-responses from Shotspotter is that RPD does not own the technology, does not maintain the records, and cannot testify as to the accuracy of the information or technology.  During my trial the representatives in California said RPD owned it and California cannot certify.  And eventually they stopped communicating with me completely.  But RPD remains firm that California owns it, and I now believe that is accurate since RPD does not, based on the representations of its own staff during my trial, have the personnel with sufficient technological skills or sophistication to run this program.

So if you have a case with Shotspotter in which you want the Shotspotter information in:

1.  Contact Shotspotter in California and ask if they have the records;.
2.  Find out who you must subpoena (see if they have a New York liaison);
3.  Do the subpoena;
4.  Do this all well in advance;
5. If you do not get a response to your subpoena for an individual to testify, consider retaining a witness from shotspotter (again, trying to use a New York representative).
6.  Review other states'  Frye cases to support your claim of admissibility.  You’ll have to ask the company to supply a list of cases because a quick Westlaw search of “shotspotter /p daubert” and “shotspotter /p frye”  failed to produce cases that addressed admissibility under Frye/Daubert.  One document that was generated but was out of my plan was “Defendant’s Memorandum of Law in Support of Motion for Frye-Mack Hearing” in State of Minnesota v. Christopher James Hayes (District of Minnesota, April 4, 2011)

If you have been unable to get the records in, you might try having the officers testify to their review of the records and listening to the recording.  (Yes – they get the records somehow.  And they listen to the recordings.)  But be aware, the same amnesia suffered by the OEC employee apparently spread to the officer on the stand, who did not recall the number of shots he heard on the audio recording, and couldn’t remember based on a review of his partner’s report.

More often, we're trying to keep the information out.  If that's the case, consider whether Shotspotter information should be admitted at any hearing or trial you are handling.  Challenge the admissibility of any Shotspotter information and request a Frye hearing.  Watch the foundations - who are they bringing in, do they keep records, do they know how the technology works.  According to the prosecutors in my case, they'd have to subpoena witnesses from the company in California to have the records, recordings, etc. admissible.  Let’s see if that’s still the prosecutors’ position when they’re trying to offer the information.  (And if it is not, please let me know!)

Whether or not you want to introduce evidence of Shotspotter activation, you will probably still want to get the records.  According to Shotspotter website entry from May 1st, the Rochester Police Department integrates the surveillance cameras with Shotspotter monitoring.  (Interesting, since they claim to have no control over the system…)  The RPD representative stated, “Integrating the ShotSpotter system with the city's video surveillance camera has enabled them to become even more effective in their response and investigations, and increasing arrests and prosecutions for crimes involving gun violence and illegal use of guns.  Immediately, when shots are fired, the camera systems start into play ... You can pick up the bad guys off the streets a lot faster because now you know exactly where you're going." - Julie Gulino, Rochester NY Police Department.

This quote can be found on the website at:

So don't forget to also subpoena camera footage from the city (with a judicial subpoena duces tecum).  This should be done as quickly as possible after entering the case - don't wait for responses from Shotspotter. You can determine whether city surveillance cameras were nearby by contacting Corporation Counsel's office. If they were, request that the RPD Corporation Counsel liaison preserve the footage, and get a quick subpoena out.
