Protection of health and safety always has a cost.   When there is a serious injury at a public facility, a lawsuit can result in changes that protect the public safety and can help prevent the reoccurrance of dangerous conditions that can result in injuries or death.   In Mexico, an outside basketball court at a school can be built on a hill where if you run off the court chasing the basket ball, you can fall off a 5 - 7 foot concrete wall and get seriously injured (I know, I have personally seen at least one of these in Mexico).  If someone gets hurts in Mexico on this type of dangerously defective basketball court, its all on you, because there is no way to hold anyone accountable.  Hence, no reason to make anything safer.   Here in the United States you would never see that type of risk being taken, because the owner of the facility can be sure that they will be held accountable for any injuries or deaths that result from the negligent design of even a basketball court.
