Repro steps:
1) Have 4000+ points.
2) When prompted to select a custom execution after being found guilty, use the keyword "jew" (Or some sentence containing that keyword, I prefer to use the sentence "jew me like a jew from New Jewsey."
3) Watch as it does the gas chamber every time, indicating that the keyword "jew" is associated with the gas chamber execution.
