Another assassination attempt on Donald Trump — this time as he played golf at one of his resorts in Florida —has prompted questions about safety, security, and how an attempt on the life of a US presidential candidate was almost  allowed to occur again.

US Secret Service agents opened fire on Sunday afternoon on a man who was spotted pointing an AK-style rifle through a fence while hiding in the bushes as Mr Trump golfed at his club in West Palm Beach.
