Link between serial killers and the military/law enforcement : TrueCrime

I have had a fascination with the psychology of serial killers for years and years (not the serial killers themselves – they are just plain monsters). One thing I’ve noticed is that many serial killers have some link or connection to law enforcement or the military (such as the Army or Navy). They have either served themselves or had a parent who has served. This seems to only be the case with American serial killers. I haven’t gone into the numbers yet but I’m planning to look into it further.

Does anyone have any theories on why this may be the case? I have my own thoughts but I’m just wondering if anyone else has noticed this.
