The wife of defendant Joaquin Guzman entered a Brooklyn courthouse on Tuesday to watch opening statements at his trial.
The defendant’s history of violence has prompted patrols by heavily armed officers outside the Brooklyn courthouse.
The jury is anonymous.

Guzman also has been held in solitary confinement and barred from seeing his wife out of concerns he could pass messages to his cohorts.
The evidence will include the testimony of more than a dozen cooperating witnesses who prosecutors say are risking retribution. There also will be evidence about multiple murders committed in drug wars in Mexico, cocaine smuggling and Guzman’s brazen escapes from jail.
His lawyers say he’s being framed by cooperators.
