What's the Process of Gathering Evidence?

Sometimes the watch will raid a house and they'll feel the bed to see if the bed's warm. There are some funny moments, like Thomas kid in love with eleanor gilderson who is already married. And there's another example of as or brothel madam, who's got a visitor with her, and the watch come, and he hides under the bed. So you get these cases that seemed to us a little bit amusing, although for the people involved at the time, i'm not sure they were all that fun. They weren't very educated people, very often, these members of the watch. And very often they neglected their duties.
