⚡ 10-Second Rule
If you help or cheer on a crime, wanting it to succeed, the law treats it as your crime too.
🧒 ELI-10 Scene
Two kids stand under Mr. Patel's apple tree. Sam climbs the fence to steal apples. Jordan holds the ladder steady and whispers, "Hurry, grab the big ones!" Jordan never touches an apple. When Mr. Patel storms out, does Jordan walk away free? No. Holding the ladder and cheering made the theft partly his. But compare Riley, who just happened to be standing on the sidewalk watching. Riley helped with nothing and wanted nothing. Watching alone gets nobody in trouble.
⚖️ Actual Rule
An accomplice is one who aids, abets, counsels, or encourages the principal before or during the crime, with dual intent: the intent to assist the principal and the intent that the principal commit the offense. An accomplice is liable for the crime itself to the same extent as the principal. Mere presence at the scene, or mere knowledge that a crime will occur, is insufficient without intentional aid or encouragement. Under the natural-and-probable-consequences doctrine, many jurisdictions extend an accomplice's liability to additional crimes of the principal that were foreseeable outgrowths of the aided crime; the Model Penal Code § 2.06 rejects that extension and limits liability to offenses the accomplice intended to promote (paraphrased), so the doctrine's status is split. To withdraw, an encourager must repudiate the encouragement, and an aider must neutralize the assistance or notify the police, before the crime becomes unstoppable. An accessory after the fact — one who assists a known felon to escape arrest, trial, or punishment after the felony is complete — commits a separate, lesser offense and is not liable for the underlying felony. Common-law terminology divided parties into principals in the first and second degree and accessories before and after the fact; modern law treats all but the accessory after the fact as principals.

🔍 Ask These Questions
- Did the defendant aid, encourage, or counsel the principal before or during the crime? (Did they actually add something — hands, words, lookout eyes?)
- Did the defendant have dual intent — intent to help and intent that the crime succeed? (Did they want the crime to work, not just know about it?)
- Is the evidence only mere presence or mere knowledge? (Just being there, or just knowing, is never enough.)
- Is the charged crime the aided one, or a natural and probable consequence of it? (Extra foreseeable crimes stick in many places — but not everywhere, so check the jurisdiction.)
- Did the defendant withdraw in time — take back the words or undo the help before it was too late? (You must unplug your own contribution while it can still matter.)
- Did the help come only after the felony ended? (Hiding a finished criminal is its own smaller crime, not a share of the big one.)
⚠️ Bar Trap
Exam language: Examiners place a defendant at the scene who knows the principal's plan, accompanies him, and silently watches, then offer answer choices convicting on presence-plus-knowledge. Absent intentional aid or encouragement given with the purpose that the crime succeed, there is no accomplice liability. The companion trap swaps timing: assistance rendered only after the felony is complete makes the defendant an accessory after the fact to a separate offense, never an accomplice to the felony itself.
ELI-10: Knowing and watching is not helping. And helping someone hide afterward is a different, smaller wrong than helping the crime happen.
🧪 Question
A college student learned that his roommate planned to shoplift a pair of designer sneakers from a mall shoe store that afternoon. Curious whether the roommate would go through with it, the student walked with him to the mall, followed him into the store, and stood silently near the entrance watching. He said nothing to the roommate inside the store, signaled nothing, and kept no lookout for security. The roommate concealed the sneakers and walked out, and both were arrested in the parking lot. The student is charged with larceny as an accomplice.
Should the student be convicted?
(A) Yes, because he knew of the plan and accompanied the roommate to the store. (B) Yes, because voluntary presence at the scene of a known crime constitutes encouragement. (C) No, because he neither aided nor encouraged the theft with intent that it succeed. (D) No, because an accomplice must receive a share of the stolen property.
Answer: (C). Accomplice liability requires an intentional act of assistance or encouragement plus the purpose that the offense succeed. The student contributed nothing — no aid, no words, no lookout — and his curiosity-driven presence and knowledge cannot substitute for either element.
💡 Why the Wrong Answers Are Wrong
- (A) rests on knowledge plus accompaniment, but knowledge is not intent and walking along is not aid or encouragement.
- (B) converts mere presence into encouragement; presence counts only when it is intended to, and does, encourage the principal.
- (D) reaches the right result on a fictional element — sharing in proceeds has never been required for accomplice liability.
- ELI-10: The misconception is thinking bystanders who knew are teammates. The law only drafts people who pitched in on purpose.
