"Justice" is the carrying out of law enforcement.
The laws do in fact exist, already, there is no debate over whether they should be in force or not. The purpose is to subvert established law, by conspiring in a group. This is criminal and it is racketeering.
Organizing to change laws is one thing, but specifically organizing to thwart laws and provide ways for individuals to escape prosecution (justice) are clearly illegal acts. I think Judicial Watch or some other such group should threaten MALDEF with a lawsuit.
