"Over the centuries many animals have been put on trial for their misdemeanors. The animal trials of the Middle Ages produced their own Perry Mason*-- a French lawyer, Bartholome Chassenee, who established a reputation for the ingenious defense of his 'clients'. In 1521 he was appointed to defend the rats which had destroyed a crop of barley. When they failed to show up for the trial (which must have been a fairly common occurrence), he successfully pleaded that the summons was invalid because it had not been served on all the rats in the district." -- From The Book of Beasts, John May and Michael Marten, The Viking Press: NY, 1982.

 *Perry Mason: created by lawyer and writer Erle Stanley Gardner, this fictional lawyer gained popularity through an American television series of the same name in the 1950's.

"What should I do?"

Directions: Read through the problem carefully. Select a reader, a writer, and a speaker within your group. Complete the chart. Share your group's recommendation with the rest of the class.

Your city has launched an aggressive anti-rat campaign. Your landlords, Rob, Joe, Susan and Wendy love to cook and use lots of canned goods and plastic bottles.  They recycle their cans and bottles in the recycling bin, but you have noticed that they don't rinse them. The recycling bin smells, and you think the food left on the cans and bottles will attract rats. In fact, you recall seeing a rat in the driveway just last night. What should you do?
