 The officers instructed Mimms to exit the vehicle; when Mimms complied, an officer noticed a bulge in his pants under his jacket, conducted a pat-down, and discovered a weapon.The officer proceeded to arrest Mimms for carrying a concealed deadly weapon and unlawfully carrying a firearm without a license, charges for which Mimms was later convicted.The conviction was reversed by the Pennsylvania Supreme Court on March 31, 1975, which ruled that the evidence should have been suppressed as the police violated Mimms' Fourth Amendment rights against unlawful search and seizure.
