Mrs Devos is not defunding or eliminating public schools.  Only states can do that.  Don't spread misinformation.  Law students that graduate from UH are required to provide x amount of hours of pro bono work so they are already doing what you suggest.  If our state leadership feels that providing legal services are a priority, then they may want to reprioritize state spending to cover it.  Or cut taxes, REALLY cut taxes, not the rate of spending and spinning it as a "cut".  Then that way, we the taxpayer can keep more of our money and use it as we see fit.  
Legal services a right?  Or a privilege?  Maybe.  6th Amendment (since 1963 ruling by SCOTUS) enumerates the requirement for "assistance of counsel" for the accused "in all criminal prosecutions."
