Zero Tolerance Has Already Failed! Abolish It!

What's the point of having zero tolerance policies if public school systems use them for minor offenses (i.e. drawing something that is percived to be threatening)?

...an autistic girl who blurted out that she wanted to kill her teacher, was
referred to juvenile services for the outburst, although she did not mean what
she said. Those kinds of incidents, he said, are disconnecting students from
their schools and communities, he said.

Many of these zero tolerance policies have already expanded from gun and illegal drug posession to minor issues. The end result is that people of color and special education students are the ones being most affected. With school suspensions and explsions rising in the Free State it's clear that Zero Tolerance has failed. Either the school boards either limit these policies to drug and gun posession and only use expulsion as a last resort, or abolish zero tolerance altogether.
