Debate on gun control is silenced yet again

Gun killings in America like the Las Vegas massacre could happen in silence if the US Congress gets its way. A bill to ease regulations on the purchase of gun silencers is gaining momentum even as the country reels from the horror of the deadliest killings in modern US history.
In fact the bill, known as the Protection of Hearing Act, was close to becoming law in June but was put to one side after another shooting outside Washington in which a congressman, Steve Scalise, was seriously injured after a gunman opened fire at a congressional baseball practice.
