From: Vignesh Ramachandran

To Whom It May Concern:

I am the managing editor of Peninsula Press, a multimedia news website based out of Stanford University in California. We are working on collecting data on traffic stops and searches made by state patrols across the country, but I'm initially gathering information about what datapoints each state collects.

Pursuant to the Connecticut Freedom of Information Act ("FOIA"), I hereby request the following records:

I’d like to please request the record layout (the format of a data record, which includes the name, type and size of each field in the record) or “data dictionary” for your state’s records of traffic stops made on your roads. (What are all the datapoints you collect and keep record of when traffic stops are made?)

I also request that, if possible and pursuant to Conn. Gen. Stat. § 1-212(d), fees be waived as I believe this request is in the public interest and not made for commercial gain. The requested documents will be processed by a representative of the news media/press and made available to the public at

The requested data will be analyzed, eventually be made available to the general public and be used for editorial purposes. This request is not being made for commercial purposes. We kindly ask the request be filled electronically — via Excel or another database format. Data can be emailed to or shared via a Dropbox link. In the event data has to be sent physically on a CD or thumb drive, please mail to Peninsula Press, Stanford Journalism Program, 450 Serra Mall, Building 120, Stanford, CA 94305.

Thank you in advance for your anticipated cooperation in this matter. I look forward to receiving your response to this request within 4 business days, as the statute requires.

Dear Vignesh Ramachandran,

In researching your request, I believe the data you are searching for is provided online by The Alvin W. Penn Racial Profiling Prohibition Act. (See first link below) You can individually search a Troop or local agency for related data and the second link provides the information in various formats. As an agency, we only collect data related to our own stops in accordance with state law for compliance under the Act. The particular data required for collection is outlined in the Act’s statutory language under Connecticut General Statutes 54-1l and 54-1m. (See third link below) The language of the statutes may assist in providing a better understanding of reporting requirements and how the Office of Policy and Management compiles data reported by law enforcement agencies. Their website also has statistical information related not only to traffic stops, but crime rates and prison populations as well. (See fourth link below)

It is my hope that this information is responsive to your request and please let me know if you have any questions or concerns.

Best Wishes,

TFC. Michael Evangelisti #774
