Each day, hundreds of schoolchildren appear before courts in Texas charged with offences such as swearing, misbehaving on the school bus or getting in to a punch-up in the playground. Children have been arrested for possessing cigarettes, wearing "inappropriate" clothes and being late for school.
In 2010, the police gave close to 300,000 "Class C misdemeanour" tickets to children as young as six in Texas for offences in and out of school, which result in fines, community service and even prison time. What was once handled with a telling-off by the teacher or a call to parents can now result in arrest and a record that may cost a young person a place in college or a job years later.
"We've taken childhood behaviour and made it criminal," said Kady Simpkins, a lawyer who represented Sarah Bustamantes. "They're kids. Disruption of class? Every time I look at this law I think: good lord, I never would have made it in school in the US. I grew up in Australia and it's just rowdy there. I don't know how these kids do it, how they go to school every day without breaking these laws."
