It's a matter of making sure the basic principles are understood. Then from there, you say what is reasonable within those principles. The law is always trying to set concrete limits, but human beings in courts work on basic principles and on what's reasonable—what a reasonable person would do, due diligence tests, and so on. Educating people on how to understand and deal with that in an area that's never seen this sort of stuff before can be a long and time-consuming process.
