I would do a search on the internet. I can't remember any resources off the top of my head, but there are several books about it and websites. If you could find the books, definitely buy them, as they're always better sources of information.
You could also go to your local animal control and get statistics from your local area. Just remember those statistics aren't going to be 100% accurate bc of obvious reasons.
I just googled 'pit bulls bite force' and a wealth of info popped up.. including psi pressure and comparisions with other breeds bite force.. Hope that helps.. have some fun searching with your keywords..
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.
