While reading your stories on UCF parking problems, I have noticed a common mistake -- the use of THAT and WHO.
So here's a reminder.
Who or whom, rather than that, should be used when the antecedent is human or when it takes on human qualities.
i.e. The police officers WHO stopped my car were polite but firm.
The candidate WHOM the voters selected has been indicted.
This is one of those pens THAT write upside down.
