With No Child Left Behind, these kids have been 'mainstreamed" into regular classrooms and whether tie kid is 12, as reported, or 15 according to other sources, you can bet he's been held back once or twice and is sharing a classroom with much younger (and smaller) kids.
Parents in this community deserve to know if a child capable of such senseless violence and destruction is in their child's classroom. There needs to be some accountability.
