I won't even try to summarize this story myself. Here are some quotes from the article.
Wabash Valley woman didn’t realize second cold medicine purchase violated drug laws
When Sally Harpold bought cold medicine for her family back in March, she never dreamed that four months later she would end up in handcuffs.
Now, Harpold is trying to clear her name of criminal charges, and she is speaking out in hopes that a law will change so others won’t endure the same embarrassment she still is facing.
Just as with any law, the public has the responsibility to know what is legal and what is not, and ignorance of the law is no excuse, the prosecutor said.
Harpold, who is employed at the Rockville Correctional Facility for women, feels her reputation has been damaged by the arrest, and that she has been wrongly labeled as someone who makes meth.
Her police mug shot ran on the front page of her local newspaper, she wrote, in a letter to the Tribune-Star, “with an article entitled, ‘17 Arrested in Drug Sweep.’”
