United States v. Bailey, 764 F.Supp.3d 342

Defendant James Leonard Bailey was indicted for possession with intent to distribute methamphetamine and unlawful possession of a firearm, arising from evidence seized during a February 28, 2024 traffic stop in Stonewood, West Virginia.
Officer Moore initiated the stop after following Bailey’s vehicle and observing Bailey make a left turn without using a turn signal while Moore was directly behind him.
Moore was aware of Bailey's prior involvement with illegal substances and had heard from other local officials that Bailey was suspected of drug activity.
After the stop, Moore and other officers discovered drugs, paraphernalia, money, and a firearm in Bailey's vehicle; Bailey made incriminating statements during a subsequent interview.
Bailey moved to suppress the evidence, arguing the stop was unconstitutional because his failure to signal did not affect other traffic; the Magistrate Judge recommended granting the motion.
The government objected, and the District Court conducted a de novo review, ultimately rejecting the Magistrate Judge's recommendation and denying the motion to suppress.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Did Moore have probable cause to stop Bailey for failing to signal?	Moore was directly behind Bailey, so may have been affected; probable cause existed.	No other traffic was affected; no violation.	Yes, Moore had probable cause to believe traffic could have been affected.
Was the stop lawful even if Officer Moore was the only other vehicle?	Yes; the law only requires the potential that other traffic "may" be affected, not certainty.	Law requires actual effect on other traffic; Moore was not affected.	The possibility that Moore "may be affected" is sufficient.
Did Moore’s knowledge of Bailey’s suspected drug activity affect the validity of the stop?	Probable cause for a traffic violation alone is enough regardless of ulterior motives.	The stop was a pretext for investigating drug activity.	Court reaffirmed stops are valid if based on any probable cause traffic violation.
Was the traffic stop a reasonable mistake of law?	No mistake; stop was supported by probable cause under current Fourth Circuit interpretation.	Mistaken stop because no legal violation occurred.	No error; officer had probable cause to believe the law was violated.
