When one of his colleagues at Mexico City’s daily newspaper was gunned down in March, Javier Valdez issued a passionate statement about the importance of the work of journalists who cover the organized crime, drug trafficking and corruption that plague Mexico. “Let them kill us all, if that is the death sentence for reporting this hell,” he tweeted. “No to silence.”

The words proved horribly prophetic when Valdez last week became the latest casualty of the drug-fueled violence that has claimed tens of thousands of Mexican lives over the past decade. His life and death should serve as inspiration and prod to the Mexican government to undertake reforms needed to end the impunity that allows the country’s lawlessness to flourish.

Valdez, 50, was shot and killed at midday May 15 on a busy street in the state of Sinaloa. Sinaloa is a trafficking destination perhaps best known as the home of Mexican drug lord Joaquín “El Chapo” Guzmán. Valdez, a correspondent for La Jornada, co-founded a regional weekly newspaper there in 2003 because of his belief in the need for honest reporting of the crime and corruption that victimize Mexicans.

He is the sixth journalist to be killed in Mexico this year and one of over 100 journalists who have been murdered since 2000. Eleven days before Valdez’s death, a delegation from the Committee to Protect Journalists met with President Enrique Peña Nieto to present its newly released report “No Excuse: Mexico Must Break Cycle of Impunity in Journalists’ Murders.” Among the recommendations were better protections for at-risk journalists, timely investigation of threats and training prosecutors in how to pursue crimes against freedom of expression.

It’s good that Peña Nieto strongly condemned Valdez’s murder, but that is clearly not enough. Recommendations of the CPJ report should be embraced, and the chronic failure of the judicial system in investigating and prosecuting crimes must be addressed.
