The Peter R. de Vries Foundation recently received a tip, which prompted the police to start looking for Germa van den Boom again. 250,000 euros have been promised for the golden tip. Do people share their golden tip after so many years just because of the reward?
According to Sven Brinkhoff, professor of criminal law at the University of Amsterdam, the relationship between money and tips is “difficult to prove”. Other motivations, such as revenge or a desire for truth, can also play a role, his research shows.
Often no tip is given that leads to an arrest. Payment was made in only 2 percent of cases in which tip money was promised.
According to Brinkhoff, tip money can cause “by-catch”. Unrest can arise from the promise of tip money. Sometimes the police tap the phones of suspects. When they talk about the case because of the unrest, this can provide new insights.
