The Brady Campaign was at the U.S. Supreme Court as the Justices heard oral arguments in District of Columbia v. Heller, the most significant Second Amendment case in nearly seventy years.

Following the arguments, Brady Campaign President Paul Helmke said that he is hopeful that the "ruling will uphold the right of people in communities like the District to enact common sense gun measures they feel are needed to protect themselves and their families."

Scenes from the steps of the Supreme Court including Brady activists and spokespeople.

The Brady Center filed a "friend of the court" brief with numerous law enforcement organizations in January that argued that the D.C. Court of Appeals ruling, if affirmed, would grant courts unprecedented authority to nullify elected officials' decisions to adopt laws they believe are necessary to protect their communities from gun violence.

The decision will be announced in June.
