When Sen. Cory Booker (D-N.J.) was a graduate student at Stanford, he wrote a newspaper column describing his anger after a jury found police officers not guilty in the beating of Rodney King in 1992.

“I’m a black man. I am 6 feet 3 inches tall and 230 pounds, just like King. Do I scare you? Am I a threat? Does your fear justify your actions? Twelve people believed it did,” Booker wrote more than 20 years ago.

In the piece, Booker touched briefly on an academic accomplishment. Then he continued: “But late one night, as I walked the streets of Palo Alto, as the police car slowed down while passing me, as his steely glare met me, I realized that to him and to so many others I am and always may be a N——: guilty till proven innocent.” (Booker used the derogatory word.)

Booker posted his column on Twitter Wednesday, which, more than 20 years later, seems to sum up many of the emotions felt by the black community after the grand jury decision not to indict Darren Wilson in the shooting death of Ferguson teen Michael Brown.

Two decades later, Booker, now a public official, wouldn’t publicly condemn the grand jury’s decision. “The rule of law is something that we have to put our faith in. There was a grand jury, they went through a process, evidence was presented for a jury and they came to that conclusion. I respect that conclusion,” Booker said, according to an article in the Jersey Journal Tuesday.

Instead, Booker said it was time to reform a criminal justice system wrought with racial inequities. On Twitter, Booker promised to continue his work with Sen. Rand Paul (R-Ky.), on their joint effort to make those changes.
