How safe will Milwaukee RNC be after Trump shooting?

Ripples from Saturday’s attempted assassination of former President Donald Trump in Butler, Pa., are being felt deeply some 550 miles away in Milwaukee, site of this week’s Republican National Convention. President Biden announced the investigation of a 20-year-old shooter’s apparent breach of a US Secret Service security perimeter at a Trump rally will be thorough, exhaustive and “independent.”

But post-incident shooting reviews are complex and take time. Congress and the American people did not get answers before the convention started Monday. Just how heightened will security measures be at the RNC? If history is an indicator, seismic shifts in posture and alertness should be underway.
