The difference a comma makes (09 feb 13)
Look at this headline:
Medford man accused of selling sex drugs from home
If it had said
Medford man accused of selling sex, drugs from home
it would have been completely different. As it is, he has been accused of selling Viagra without a license. With the comma, it would be a lot worse.
