接上段，请翻译一下，不胜感激 Would any of these actions have prevented the Newtown tragedy? It's unlikely any gun laws passed this year would have prevented Adam Lanza from carrying out the killings at Sandy Hook Elementary School. He used guns and ammunition purchased legally by his mother. He had been evaluated by mental health professionals who told her he was not a risk to himself or to others. However, the Bushmaster Model XM15-E2S rifle he used is no longer available for purchase in Connecticut under the state's new assault weapons ban. To mark the one-year anniversary of the shootings, Connecticut Gov. Dannel P. Malloy has asked that houses of worship ring bells 26 times at 9:30 a.m. on Saturday morning. Gun control groups organized by Obama's campaign group, Organizing for Action, will mark the day with rallies encouraging lawmakers to toughen gun laws.
