Jakarta, Jakarta, Indonesia. 6th Jan, 2014. Each day before dawn the repairmen sabotage streets by dumping hundreds of nails and other sharp objects before setting up roadside workshops. For the tyre repairmen who work in pairs, earnings of about 300,000 rupiah ($29) to 500,000 rupiah a day are normal. It is good business in a country where nearly half the 240-million population lives on less than $2 a day. But alongside police, in a country known for crooked law enforcers and widespread corruption, is a team of dedicated volunteers determined to deflate the repairmen's profits.
