Depending on where you live and in what jurisdiction you'll be working, you may have to be a regular uniformed police officer for a couple years first before being considered for the CS team. All of the jurisdictions around me that I have asked have told me the same thing. Once you've been a cop for two years, then you can start looking into the special assignments.
There is such a thing as a forensic photographer so disregard the comment that said otherwise. I considered becoming a forensic photographer---there are some colleges (in florida) that offer forensic photography as a minor/major---but usually, colleges don't do that. There are two schools that I know of that offer this course---of which I forgot their names (sorry) This is all I know about the subject so sorry for not being able to tell you what you wanted...
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
