Eckert's attorney, Shannon Kennedy, said in an interview with KOB that after law enforcement asked him to step out of the vehicle, he appeared to be clenching his buttocks. Law enforcement thought that was probable cause to suspect that Eckert was hiding narcotics in his anal cavity. While officers detained Eckert, they secured a search warrant from a judge that allowed for an anal cavity search.
It gets much, much worse...
EDIT: And just to show there isn't any gender bias on the vigilance.
