Most Americans were horrified and heartbroken on behalf of Charlie Kirk's family after the 31-year-old conservative activist was murdered last week.

They included Supreme Court Justice Amy Coney Barrett, who spoke out regarding Kirk's assassination on Friday. 

Supreme Court justice condemns political violence as "grotesque"

According to The Hill, Barrett's remarks came as she spoke at the University of Notre Dame to promote her new book titled, "Listening to the Law: Reflections on the Court and Constitution."

"Too often when I look around the country, political violence is the most grotesque symptom of it, but there are others, too, just in online conversations and the way that people treat those with whom they disagree," Barrett said with respect to the rejection of civility.

"And that’s actually one of the points that I try to make in the book is that’s just not a way to run a society," she explained.

When it came to her own wellbeing, the Supreme Court asserted, "I'm in very good hands, so I feel safe, but we do have round-the-clock security."

Barrett's sister was subjected to a bomb threat

Barrett's family is no stranger to the prospect of political violence, as her sister was subjected to a bomb threat earlier this year.

As Fox Carolina News reported this past March, police officers in Charleston, South Carolina responded to the home of Amanda Coney Williams.

Williams' husband told police he had received an email which contained detailed information concerning an explosive device and referenced events in the Middle East.

"Using a 1x8-inch threaded galvanized pipe, end caps, a kitchen timer, some wires, metal clips and homemade black powder, I've constructed a pipe bomb which I recently placed in Amy Coney Barrett's sister's mailbox at her home in Charleston, SC. The device's detonation will be triggered as soon as the mailbox is next opened. Free Palestine!" it read.

Fox Carolina pointed out that although emergency personnel carried out an inspection of the couple's mailbox, no explosive device was found.

Man who tried to assassinate Justice Brett Kavanaugh pleads guilty

Meanwhile, Justice Brett Kavanaugh was targeted for assassination in 2022 shortly after the Supreme Court overturned Roe v. Wade.

A Department of Justice (DOJ) press release detailed in April how Nicholas John Roske pleaded guilty to Kavanaugh's attempted killing.

Roske was taken into custody outside of Kavanaugh's Maryland home, with police discovering a firearm as well as other weapons.
