The whole trial to me was a defiantly a case of entrapment. Portia seemed to actually knew what she was trying to do through the whole trial. The way that Portia talks to Shylock about the lease his her way of trapping him in to the bond. Shylock is wanting to stick to the bond as closely as possible and Portia knows this. She even leads Shylock to believe that he is going to get his pound of flesh because the bond says so. But she must have been thinking ahead when she said this because she knew the laws. If Shylock was to take more then a pound of flesh and spill the blood of a christian Shylocks life would be taken. Portia knew that these things are inevitable when cutting flesh, thus creating doubt in Shylocks mind. She was about to use her knowledge of the law to play it against Shylock, and was about to trap him self into backing out. Making Antonio look as if he was really going to pay the debt with his flesh and that he was not the coward, but that Shylock was the instead the coward.
