People v. Gleghorn

A man whom you threatened to beat
Volleyed an arrow to greet
His hint was the flight
When you start the fight:
To claim self-defense, first retreat

People v. Gleghorn, 193 Cal.App.3d 196 (1987)
(no right to self-defense against another's response to a person's own aggression, unless the person first retreats).

Regina v. Faulkner

While out to purloin some libation
A sailor did cause conflagration
Should unlawful objective
Grow the aim of corrective?
The verdict below saw negation.

Regina v. Faulkner, 13 Cox C.C. 550
(Hat Tip: F. M. '12)

Chicago v. Morales

Hangin' 'round without purpose apparent
In Chicago offends law not transparent
To fight a crime plague
They made law that's vague
The court ruled the ordinance errant.

Chicago v. Morales, 527 U.S. 41 (1999)
(loitering law held unconstitutionally vague).

Proctor v. State

Selling booze was a landlord's intention
Against which the State sought prevention
But they made as their actus
A quite lawful practice
The court would not buy that contention

Proctor v. State, 176 P. 771, 15 Okla. Crim. 338 (1918).
