Five achingly obvious security blunders in Trump assassination bid from not securing vantage point to cops RETREATING

A SERIES of glaringly obvious security blunders at Donald Trump's rally have raised questions after the former President was almost killed.

Millions have been left baffled after a lone gunman managed to get within a few hundred feet of Trump before unleashing a spray of bullets, missing his head by mere centimetres.

And a series of concerning reports have surfaced in the hours since Trump was grazed by one of his bullets.

It has been claimed that Secret Service agents failed to properly secure the area ahead of the event, even after flagging the shooter's perch as a security risk.

Supporters in the crowd allegedly alerted police to the man, crawling onto a nearby building with a rifle in hand, and were ignored.
