Media are reading this as a threat against Clinton, which requires reading more into it than was there.
Via The Hill:
Republican presidential nominee Donald Trump appeared to joke about the possibility that Hillary Clinton could be shot in remarks at a campaign rally Tuesday in Wilmington, N.C.
Trump was discussing the possibility that Clinton, the Democratic nominee, would be able to appoint liberal justices to the Supreme Court if she wins the race for the White House.
He then said that there was nothing that could be done in that scenario, before mentioning “Second Amendment folks.”
“Hillary wants to abolish, essentially abolish the Second Amendment,” Trump said to boos from the crowd.
“By the way, if she gets to pick her judges, nothing you can do folks,” he then added.
“Though the Second Amendment people, maybe there is, I don’t know.”
After the comments won significant attention, the Trump campaign released a statement saying that Trump was referring to how the National Rifle Association and other backers of the Second Amendment had the political power to stop Clinton at the polls.
They also blamed the media for distorting Trump’s comments.
