Pennsylvania town aims for normality as police feel heat over Trump shooting

Residents of Butler keen to put assassination attempt behind them amid swirl of questions over security lapses

Three days after Donald Trump came close to being assassinated by a sniper's bullet, the town of Butler, Pennsylvania, was attempting to return to normality as questions continue to swirl about security lapses that preceded the shooting.

It is now believed that Thomas Crooks, the 20-year-old suspect, was spotted by law enforcement officials on the roof of a glass research company at 5.45pm, nearly 30 minutes before shots were fired that injured Trump, killed a former fire chief and injured two others in the crowd.
