US teacher suspended after racy Twitter photos Carly McKinney, a 23-year-old mathematics teacher at Overland High School in Aurora, Colorado, was placed on administrative leave after school officials discovered her Twitter account was filled with racy pictures and comments about drug use. It reads: "Watching a drug bust go down in the parking lot. It's funny cuz I have weed in my car in the staff parking lot. A spokesman for the Cherry Creek School district said that it was the posts about drugs on school property which formed the basis of the investigation. The spokesman said: "The three posts that we are most concerned about are the ones that may indicate that she violated school policy and/or law. Adults can smoke marijuana in Colorado. But it is still against state and federal law to use or possess (marijuana) on school property. The spokesman added that the school was not investigating the photographs, saying that Miss McKinney's First Amendment rights entitled her to post such images on a personal account. Miss McKinney was placed on paid administrative leave on Tuesday.
