I agree, it would be less than noble for an officer to off themselves while implicating suspects and creating a bunch of chaos. But we have to consider the contrast between the legacies of an officer thought of as being killed in the line of duty and one that simply crashed his car or shot himself while cleaning his weapon. In my view, we have to take into account what the big picture intentions might have been and not just the fastest way out. Judging by the tattoos and such, It's obvious that the Lieutenant was far more obsessed with his image as a police officer than most cops are.
Wouldn't the tattoos be more from his military background than his LE background? One thing I haven't seen discussed is how his military background might play into this? How did it affect him, etc. ?
