Reckless endangerment.

http://en.wikipedia.org/wiki/Reckless_endangerment 

Reckless endangerment: A person commits the crime of reckless endangerment if the person recklessly engages in conduct which creates a substantial risk of serious physical injury to another person. “Reckless” conduct is conduct that exhibits a culpable disregard of foreseeable consequences to others from the act or omission involved. The accused need not intentionally cause a resulting harm or know that his conduct is substantially certain to cause that result. The ultimate question is whether, under all the circumstances, the accused’s conduct was of that heedless nature that made it actually or imminently dangerous to the rights or safety of others.

This is what is happening with the present prohibition policies. Here are some examples of it:
