Here is an interesting story from Jacksonville, Florida. A disgruntled employee at an architectural firm purposefully deleted seven years worth of files, estimated to be worth $2.5 million, when she mistakenly thought she was about to be fired. She was arrested and charged with causing greater than $1000 damage to computer files, which is a felony in Florida. The business owner did eventually recover the files but only at a great expense.
