This might be one of the worst excuses we've ever heard from a criminal. And that's saying something . . .
Cops in Fort Pierce, Florida pulled a car over last month after they saw it swerving around the road.
26-year-old Kennecia Posey was the driver. They ended up finding a bag of pot in her purse, and she admitted it was hers. But they also found a bag of cocaine . . .
And when they asked her about it, here's what she came up with: She talked about how windy it was that day . . . and said it must have, quote, "flown through the window and into [her] purse."
She's facing a misdemeanor charge for the marijuana, and one felony count for possession of cocaine.
