From another article (since I wasn't caught up to the affairs of the Netherlands):

> Crime reporter de Vries acted as a spokesperson and non-legal advisor for crown witness Nabil B. who is testifying against Ridouan Taghi, the alleged mastermind of the Amsterdam-based group which is seen as one of the Netherlands' largest cocaine distributors.

> Two people close to Nabil B. are already dead, allegedly murdered by Taghi's associates. In 2018, Nabil B.'s brother was murdered in broad daylight in Amsterdam and in 2019 his lawyer Derk Wiersum was gunned down outside his home.

> De Vries' work exposing the underworld has resulted in repeated death threats. Dutch newspaper De Telegraaf, where de Vries started his career, says he investigated more than 500 murders. In 2019, the journalist said he was on Taghi's hitlist.
