I didn’t just read this case. I used it. More than once. And you know what? It stuck.
What this case is (in plain talk)
Morissette v. United States is a Supreme Court case from 1952. A junk dealer picked up old bomb casings from an Air Force range. He flattened them and sold the metal for $84. He thought the stuff was abandoned. The government said he “knowingly converted” federal property. Big words. But here’s the heart: did he mean to steal? For a deeper, hands-on breakdown of the opinion, you can also read this practical take on Morissette v. United States.
The Court said this kind of crime needs intent. The fancy term is mens rea. If a law sounds like a normal theft law, the Court wants proof of a guilty mind. Not just proof that you took something. That part matters a lot.

How I used it in real life
- First time: 1L Criminal Law. I read the opinion twice. I underlined the part where Justice Jackson said we don’t turn common crimes into “no-intent” crimes. That line helped me pass my cold call without sweating through my sweater.
- Second time: summer at a public defender’s office. I wrote a short memo on a scrap-metal case. A guy took pallets from behind a store. He thought they were trash. I flagged Morissette to show why intent mattered. The charge changed. The tone in the room changed too. For another first-person account of how this scrap-metal theme can stick with you, check out this narrative take.
- Third time: my neighbor grabbed a “free” lawn chair by the curb. Turns out it wasn’t free. The owner was mad. I explained the idea from this case: if you make an honest mistake, that matters. I’m not a lawyer, but the idea helped folks calm down and talk it out.
The story beats that hit hard
- The man didn’t hide. He asked around and thought the casings were junk. That detail feels human.
- The jury was told intent didn’t matter. That felt wrong in my gut before I knew the law.
- The Supreme Court fixed it. They said, for crimes like theft, we usually need intent. Simple and fair.
What worked for me
- Clear rule for real life: intent counts in classic crimes like theft and conversion.
- Easy to teach: I used this case to explain mens rea to my cousin in 10 minutes. We were at the kitchen table with iced tea and a highlighter.
- Good writing: old-fashioned, yes, but clean. You can hear the logic walk.
What bugged me a little
- It’s an older case. Some parts feel dated. You may need a quick pause and a sip of coffee.
- It draws a line between “public safety” laws (which can be strict) and normal crimes. That line can blur in modern cases. So people still argue about it.
- If you only skim, you might miss that the statute said “knowingly converts.” The fight was about what “knowingly” really means. Words matter here.
Real-world moments where it helped me think
- Curbside “free” piles: Is it trash or not? If you grab it with a good-faith belief it’s free, that belief matters.
- Warehouse pallets: Lots of folks think old pallets are fair game. Some are. Some aren’t. Intent and signs and routine matter.
- Lost-and-found at work: If you keep a phone you thought was abandoned, that’s different from hiding it on purpose. Same act, different mind.
Little study tricks I used
- I read the case on Cornell’s site, then listened to Oyez notes while I cooked pasta. Hearing it twice made it stick.
- I made a one-line card: “Traditional crimes need intent unless Congress is super clear.” That card lived in my bag for exams.
- I color-coded: facts in blue, rule in green, policy in orange. It sounds silly, but it works.
Outside the law library, the power of clearly stated intent pops up in relationships too. If two adults agree up front that they’re only looking for a casual connection, everyone is on the same page—no hidden expectations to “convert” later.

Similarly, if you’re curious about how today’s classified-ad spaces balance clear consent with legal safeguards—a modern echo of Morissette’s “intent matters” lesson—visit the local-focused Backpage Harvey listings where transparent posting rules and upfront disclaimers show how spelling out intentions can keep interactions consensual and above board.
Need a different case to practice the same study tricks? I boiled down another intent-heavy decision over here: I read Delligatti v. United States so you don't have to.
Who should read this
- Law students who want a clean anchor for mens rea.
- Public defenders and clinic folks who see honest-mistake cases.
- Compliance people who write signs like “Not Trash — Do Not Take.” Clear signs can save a long day.
A quick “so what”
Here’s the thing: Morissette tells us the mind matters. Not every wrong is a crime. Not every mistake makes you a thief. That’s both simple and deep.
My bottom line
I’d call this case a keeper. It’s fair. It’s useful. It’s sticky in your brain. The writing shows respect for common sense. I’ve leaned on it in class, in work, and in real life chats. If you need one case to explain mens rea for theft-style crimes, this is the one.
And if you ever see a “free” sign by the curb? Maybe ask twice. Morissette would smile at that.
