More than 100,000 people attended the memorial service for US political activist Charlie Kirk in Glendale, Arizona, where organisers introduced heightened precautions, including bulletproof glass at the podiums used by US President Donald Trump and other high-profile speakers.
The funeral was designated a Special Event Assessment Rating (SEAR) Level 1, the highest US security status short of a presidential inauguration. The scale of the memorial and the presence of prominent figures prompted questions about whether there was specific intelligence of a threat against Trump or whether the measures reflected standard protocol.
