Santiago is a mental patient and yet he was able to get a gun. Law enforcement reports that he had several arrests because he was doing crazy shit yet he was able to get a gun. I blame his doctors and if anyone should be put to death for this it should be members of the medical industry who drug the shit out of crazy people while ignoring the fact that these people are dangerous.
As soon as some White Coat Mafia scumbag puts some nut job on medication they should ask if that person has firearms or access to firearms. Psych meds often make crazy people violent.
