How did security miss the Trump shooter?

Thomas Matthew Crooks, the 20-year-old shot dead by a secret service sniper following the attempt on former president Trump’s life at Butler, Pennsylvania, had donated $15 to ActBlue, a political action committee which raises money for Democratic causes. State voter records also show that Crooks was a registered Republican. Either way, it is too early to be certain of his motive.

What we do know is that since 9/11, domestic terror plots have outstripped the threat from al-Qaeda and Isis in the US, accounting for more than half the deaths. Government data reveals that incidents of domestic terrorism increased by 357 per cent between 2013 and 2021. Most of that threat is from the far right. Right-wing extremists perpetrated two-thirds of the attacks and plots in the United States in 2019 and over 90 per cent between 1 January and 8 May 2020, according to the Center for Strategic and International Studies at Georgetown University.
