A nice summary of events posted on The Bulwark about the man Abbott just pardoned.
"In the summer of 2020, a Texas man named Daniel Perry was watching the Black Lives Matter protests unfolding across the country with a sense of deep rage. “I might go to Dallas to shoot looters,” he texted one friend. “I might have to kill a few people on my way to work they are rioting outside my apartment complex,” he wrote to another. “No protesters go near me or my car.”
A few weeks later, Perry drove his car into a crowd of people at a Black Lives Matter march in Austin, Texas, running a red light with tires screeching, leaning on his horn, and nearly hitting several. As several protesters angrily punched the car that had nearly hit them, another marcher, Garrett Foster, walked up to Perry’s car window to speak with him. Foster was legally carrying a rifle. Perry shot him five times."
