I love a happy ending!
I see an opportunity for legal justice. This poor, misunderstood, crime specialist was just trying to earn a buck. The owners of this retaining wall should be jailed. 3 feet is entirely inadequate to protect crime specialists from injury and death when completing their work. There should have been brightly lit signs in a 100 languages warning of the possible danger. There should be warnings for the visually or acoustically challenged crime specialists. The wall should not have been scalable. The city council needs to enact new building codes to ensure that this situation can never be repeated again. The city should immediately hire a new army of inspectors to test each wall.
