The Use of Minors as Confidential Informants

Serving as a confidential informant can be dangerous, whether the informant is an adult or underage. As to minors working as informants, the International Association of Chiefs of Police recounts a cautionary tale:

In 1998, police in California arrested [17-year-old Chad] MacDonald on drug charges. He agreed to act as a CI, wearing a recording device during at least one drug buy and providing police with information about local drug trafficking. A short time later, he was found dead in an alley, apparently tortured and strangled, and his girlfriend was found raped and shot to death in a canyon. MacDonald’s death was believed to have been the result of his association with law enforcement as a CI.

Bearing these risks in mind, is it lawful for police to use minors as confidential informants? Is it a good idea? This post explores the topic.

News Roundup

The top national story this week is that the Supreme Court just heard oral argument in a case involving a shocking error by law enforcement. In 2017, an FBI SWAT team smashed its way into an Atlanta home and discharged a flashbang grenade in a pre-dawn raid. I believe the technical term for what happened is that they scared the bejeezus out of the couple and young child who were sleeping there . . . only to find out that they had entered the wrong residence. The warrant authorizing the intrusion was for 3741 Landau Lane, but they had entered 3756 Denville Trace. The residents sued under the Federal Tort Claims Act, the government contended that something called the “discretionary function exception” barred recovery, and lower courts ruled for the government. The Supreme Court granted review and heard arguments this week. According to SCOTUSblog, the Court “was sympathetic” to the residents but the outcome of the case remains unclear.

May an Undercover Officer Engage in Sexual Activity with a Suspected Prostitute?

I read a news article some time ago about officers who investigate suspected prostitutes by going undercover and purchasing their services. The article noted that this practice is controversial. Some agencies apparently don’t allow it, deeming it unnecessary and dehumanizing; others allow brief sexual contact but then require the officer to desist; and still others allow officers to engage in extended sexual contact. Similar issues arise when officers use informants to procure sexual services. A premise of the article was that there is no legal impediment to such practices, but the actual legal landscape is more mixed. This post provides more nuance.

Supreme Court Upholds ATF Regulation Defining Gun “Parts Kits” as Firearms

A couple of weeks ago, the Supreme Court decided Bondi v. VanDerStok, 604 U.S. __ (2025). It is an administrative law case, not a Second Amendment case, but folks interested in firearms law will still want to know about it. The media has generally described this case as allowing the ATF to ban “ghost guns,” which is not exactly wrong but also is not precise. Read on for more details.

When Can the Police Seize a Cell Phone Incident to Arrest, and How Long Can They Keep It?

Riley v. California, 573 U.S. 373 (2014), holds that the contents of a cell phone may not be searched incident to arrest, but allows for the possibility that the phone itself may be seized incident to arrest. This post addresses when such a seizure is permissible and how long it may last.

News Roundup

The news story that captured my attention this week is not exactly, or not entirely, a criminal law story. Mahmoud Khalil, who helped lead pro-Palestinian protests at Columbia University, was arrested this week by ICE agents at the university-owned apartment where he lived. (Khalil apparently was a graduate student at the university until December.) Khalil is a lawful permanent resident of the United States – that is, a green card holder – but the agents indicated that his status would be revoked as a result of what the Trump administration views as his anti-Semitic advocacy. He remains in custody but has lawyered up, raising interesting questions about the government’s ability to revoke legal permanent residency based on speech. A federal judge has ordered that he not be deported pending further proceedings. The AP has more here and here. Keep reading for more news.

Children and Consent Searches

Some time ago, I received an email from a researcher asking whether a minor may consent to the search of his or her cell phone. The question made me realize how little I knew about children’s authority to consent to searches more generally. So I cracked some law books, and wrote this post as a primer for anyone who may be as uninformed as I was.

News Roundup

Tuesday night, Pam Bondi was confirmed by the United States Senate as the Attorney General of the United States. Bondi previously served as Attorney General of Florida. The Senate voted 54 – 46, with all Republicans plus John Fetterman of Pennsylvania voting in favor of confirmation, and all other Democrats voting against. NPR reports here that Bondi immediately issued 14 memoranda that, among other things, lift the federal moratorium on executions; establish a task force on antisemitism and justice for the victims of Hamas’s October 7, 2023, attack on Israel; and form a working group regarding the weaponization of federal agencies for political ends.

Book Review: Framed

I’ve enjoyed quite a few books by John Grisham. I liked some of his early fiction a great deal. His more recent novels have been hit or miss for me. This Christmas, I received a copy of Framed, a new work of nonfiction he wrote in collaboration with Jim McCloskey, the founder of a nonprofit called Centurion Ministries that works to exonerate the wrongfully convicted. The book has ten chapters. Each tells the story of a wrongful conviction. I found the book interesting and also somewhat unsatisfying, for reasons I explain below.

Law Enforcement Officer Standards, Selection, and Training: How We Compare to Spain

I recently had the opportunity to travel to Spain, where I networked with academic colleagues, gave a talk about American policing, and did some research. One thing I wanted to learn more about was how law enforcement officers in Spain are selected and trained. I had read this article, and similar pieces, arguing that police training in Europe is very different from – and superior to – American police training. I wanted to assess that for myself. I was surprised by some of things I learned, and I thought I would share them in this post.
