GUYS!!! Stop saying Coyle is singing his ABCs wrong!!
"T, P, D, A, T, F, C, I, A, F, B, I, U, S, P, I, S, D, O, D, S, S, S, U, S, A."
He's not singing his ABCs he's just using the same tune, they're all acronyms
ATF = Bureau of Alcohol, Tobacco, Firearms and Explosives
CIA = Central Intelligence Agency,
FBI = Federal Bureau of Investigation,
USPIS = United States Postal Inspection Service,
DOD = United States Department of Defense,
SSS = Selective Service System,
USA = United States of America
Okay? So let's all stop saying he's uneducated or illiterate because he's definitely not. Pre-Sinyala Coyle kept "obsessively complete notes" according to Clyde Perry's account, and furthermore just look at his pretty handwriting on the evidence boxes, that's not an uneducated scrawl. Coyle is willfully ignorant, but he's not lacking in basic literacy skills.
"But Leon, why did he misspell Guilty as Giltee on the Scapegoat?"
Well, friend, I don't entirely know. But as he's spelt it correctly in other places, he probably did it on purpose, matching his dialect to emphasise his point. Maybe he just forgot about the U and by the time he'd started carving the L he knew he needed to commit to his fuck up.
*Sooo I have some theories as to what TPD could stand for.
Total Permanent Disability. In one of Coyles' dialogues, he mentions his Father losing his foot in the Battle of Hürtgen Forest. That injury would likely see him permanently disabled and unable to work as he had before (it's implied that Coyles' parents were cattle ranchers), therefore he would be entitled to welfare checks.
Tulsa Police Department. Tulsa and Blackwell are within 2 hours drive of each other and it's very possible that Coyle completed his training at the Tulsa Police Academy before going on to work for the Blackwell Police Department. Tulsa also has history of violent racism, which would appeal to Coyle.
Tactical PSYOPS Detachment/United States Psychological Operations. There was extensive use of psychological operations in World War II, and given everything that the Outlast Trials are about I think this is a worthy contender.
Tobacco Products Directive. This was the only other thing I could think of that would make sense in conjunction with Coyle, but it's a European Union directive, and therefore I think it's unlikely this is what Coyle is referring to, but I still thought it was worth mentioning.
If you have any better ideas please feel free to share them!
A big big thank you to my friends in the Coyle Crew: @misa-bun @soggy-bean and @mortisdeth for their help in researching, theorising and giving me moral support when I thought I was about to lose it
