Gun control advocates are urging lawmakers to rewrite the nation’s gun control laws after mass shootings in upstate New York, Pittsburgh and Washington state. In Binghamton, New York, a gunman attacked an immigration center on Friday, killing thirteen people before taking his own life. Most of the dead were immigrants who were taking classes at the immigration center. The gunman was a Vietnamese-born immigrant who recently lost his job.

Binghamton Police Chief Joseph Zikuski: “What we do know is Mr. Wong arrived at that residence wearing body armor, which would tell us that at one point in his thinking process he was going to take the police on or at least try to stop us from stopping him. He must have been a coward. We speculate when he heard the sirens that he decided to end his own life, so that’s what — he was heavily armed, had a lot of ammunition on him. And thank God, before more lives were lost, that he decided to do that.”

On Saturday in Pittsburgh, three police officers were shot dead as they responded to a domestic violence call. Meanwhile, in Washington state a thirty-four-year-old man shot dead his five children on Saturday before killing himself. The children were between the ages of seven and sixteen. There was also a series of high-profile mass shootings last month in North Carolina, California and Alabama that killed a total of twenty-three people. Paul Helmke, President of the Brady Campaign to Prevent Gun Violence, said, “The laws on the books aren’t getting the job done. Now is the time to take effective steps to prevent gun violence.” According to the Brady Campaign, about 30,000 people die every year in the United States from gun violence. That’s about eighty people a day.
