I agree wholeheartedly, that he saved the state a ton of money. By my rough calculations it costs 30K a year to house a prisoner. Given the nature of the crime they were automatically looking at life in prison, I’m guessing they were relatively young (under 30yrs old) so they could easily have spent 35-40 years behind bars. That’s $1,050,000 - $1,200,000 just to house one prisoner for that amount of time. Multiply that by 3 and you get: 3, 150,000 - 3,600,000 and that’s not even adjusted for inflation, including appeals courts, or any health issues they may develop as they age.
Instead of the state paying him, (because in reality the state has no money, it doesn’t first take from some other tax paying American) he shouldn’t have to pay taxes on anything ever again until he uses up the 3.6 million - 4 million tax credit he saved the state of Texas.
The only problem I can foresee with this program is that otherwise good people will begin trying murder a criminal for the tax benefits. Instead of shooting until the criminal no longer poses a threat, I fear some will continue shooting until the criminal is dead.
