Please analyze the following short fact patterns with an eye toward deciding whether strict liability or negligence (1) should apply and (2) does apply as a matter of law: John is playing with his pet dog in his front yard. The dog sees a child across the street and, without warning, runs toward the child and knocks her over, causing various bruises. John's pet alligator escapes from his backyard and bites his neighbor. A high-tech manufacturing corporation is testing a new technology for using microwaves to improve data density on hard drives, and their experiment causes a metal shard to fly out of their window and hit a passerby across the street, 700 feet away. There was no specific reason the company should have expected this to happen.
