Heh, I have a vampire with intense Day Phobia doing the detective career. He's not exactly enjoying it (always tense) but I'm having fun teasing him. He's definitely the bad cop taking out his frustration on people around him and if he sometimes wants to use the inmates as plasma packs then... oh well. Vampire powers can be handy since you can e.g. use Detect Personality to figure out the traits of the suspects.

Besides him being tense all the time (which was my choice since I picked that weakness for him) he can still operate just fine. Though patrolling is something he currently needs to forget about (well, unless you get lucky and it's cloudy) but he should be able to do that in the future when I max out Sun Resistance perk or perhaps mix some sun resistance potions.
