How violent are liberal democracies these days? Authorities in the US are investigating what is possibly the second assassination attempt against Donald Trump of this presidential election campaign.

We ask about the probe and whether a link exists between violent rhetoric and actual acts of violence. From the assassination of Japan's former leader Shinzo Abe to the recent attempt on the life of Slovakia's Prime Minister Robert Fico, each example is different.

But is there something about America, the land of gun rights and the pioneer spirit of the Wild West, that makes it unique among Western powers? What impact does this violence have on voters? And when they count the ballots, will the pen be mightier than the sword?
