We receive many calls over the course of the year from potential clients, telling us they received a “target letter” from the U.S. Attorney’s Office or State Attorney General’s Office and that they are considering whether to go to an interview with law enforcement under a “proffer agreement.”
I have written a number of times about modern technology being used in criminal investigations, from cellphone towers tracking our phones, to Alexa and other smart home devices used to record internet searches and conversations, to security cameras used to spy on their homeowners. Recently, the New York Times and other media outlets reported that Google has the ability to track which cellphones are in the area of a crime scene at a particular time. Once law enforcement narrows down which phones they are interested in, they obtain a warrant for the particular cellphone owner’s information.
Recent cases continue to reveal the advancements in technology and how they are used, both properly and improperly, to track our movements, actions and private lives. First, new cars have increasingly sophisticated technology. Roadside assistance features and other devices track our vehicles’ locations, speed and other relevant activities. Most vehicles are now equipped with Event Data Recorders, also known as a vehicle black box. Local police departments are now equipped to retrieve and analyze the black box data and use it against you in court. As of May 2018, almost all U.S. vehicles come standard with a black box installed.
The U.S. Securities and Exchange Commission (SEC) operates from its headquarters in Washington, D.C. and has 11 regional offices. It’s Division of Enforcement investigates cases and recommends to the Commission cases to be brought against individuals and entities. Investigations can begin through whistleblowers, news articles, referrals from other agencies, complaints from the public or data derived from market surveillance.
A federal or state agent or detective knocks on your door at 6 a.m. and serves you with a grand jury subpoena for documents and/or testimony. Do you simply gather the documents requested and send them to the U.S. Attorney’s Office or the County Prosecutor’s Office, or do you retain experienced criminal defense counsel? If the subpoena requires testimony, what rights do you have?
Over the past several months I have written about the increasing use of every day technology that automatically tracks our movements and records our conversations. Cellphones ping off cell towers that give the government access to our daily movements through information stored by carriers like Verizon, AT&T and Sprint. Alexa and other smart home devices can record our conversations and keep track of our search histories. Smart phone apps and Fitbits that track movement, heart rates and other physical activity can be used to track locations, times and other physical attributes that law enforcement can access to investigate a variety of crimes.
With the legalization of marijuana for recreational and medicinal uses across the country, police and legislators are scrambling for accurate devices that can detect a person’s impairment for driving under the influence of marijuana. Most law enforcement agencies rely on observation and specific cognitive and field balance tests by certified drug recognition experts (DRE). However, none are scientifically accurate to detect the level of impairment.
Last week’s decision in Carpenter v. United States, a 5-4 decision that the government must obtain a court-authorized warrant for cell site location information (CSLI), is a small step toward recognizing privacy rights in an age of ever-expanding technology. Most people do not realize that their cell phones are capable of tracking their every movement - 24 hours a day, 7 days a week. As we move about, our cell phones ping off of the nearest cell tower. Several times a minute our cell phones contact the nearest cell tower. Our cell providers collect and store that information. Examining that information can reveal a person’s daily movements with a fair degree of accuracy, usually within hundreds of feet to a few miles. Each tower has time-stamped records for every cell phone that pinged off of it, and more specifically, which direction on the tower’s multiple receivers.
Headlines and tweets coming out of Washington have put a spotlight on law enforcement’s use of informants, now known in federal parlance as “confidential human sources” or CHS. Putting aside the political theater and self-serving spin of the “criminal deep state” and the planting of spies, how are informants used in every day investigations?
Using human sources (informants) to collect information is common throughout municipal, state and federal investigations. Informants are either individuals who have been charged with their own crimes and have agreed to cooperate in the hopes for reduced charges or sentence based upon that cooperation, or are people who are paid for their information and access to criminal groups or activities. The use of confidential human sources is expressly encouraged by the guidelines that cover the FBI’s behavior.
While most people consider themselves unlikely to become the subject of a police investigation, there is one common situation in which ordinary citizens fall under police scrutiny: the traffic stop. Police officers are trained to search for evidence of illegal activity every time they pull over a driver, whatever the reason for the stop. While the consequences for speeding, failure to maintain lane, careless driving or Driving Under the Influence (DUI) can be bad enough – carrying the possibility of loss of driving privileges, assessment of motor vehicle points and higher insurance rates – things become far more serious if the police search for and find illegal drugs in a car. Teenagers and young adults – who are presumed by police to be more likely to be in possession of illegal recreational drugs – are often the targets of such searches late at night, while driving to and from wherever it is that teenagers actually disappear to when they leave the house to “hang out with friends.”
