Now that is a prudent use of government funds, that is. Definitely a wise public service announcement. Just think what could occur if an elderly couple picked up the wrong hitchhiker along this stretch of highway. Not all recent parolees have made a vow to go straight, and the wrong parolee could easily ruin your day.
But one really has to be an optimist to pick up a hitchhiker in any event in this modern day. Hitchhikers would generally be considered to be folks who are a little short of funds. And it stands to reason that someone who is down and out may be more apt to bend the law if it suits his purpose simply because he has less to lose. At least that is one school of thought.
