The libs passed laws stating that this was the only allowable method of execution. Anything else is too inhumane and violent for these despicable murderers, whom liberals adopt as their pets. What they want is no executions at all and a return of roulette wheel justice where violent criminals are released into the population to maim and murder at will, like in late 1970’s California.
Liberals are insane. And the Asspress is doubly insane.
actually - laws (and Supreme Court decisions) have validated as still legal:
Lethal injection
firing squad
hanging
gas chamber
