As for the security - outward swinging doors are easier to break into - the hinges are exposed, and even security hinges aren't that difficult to remove...
I'm curious how you would remove a hinge with the door closed?
Exterior or interior hinge pins can be removed.
The jam pin with a keyed deadbolt removes that opportunity (at least makes it very hard) to slide/slip/pry the door out.
It's all about making the thief go to the neighbors.
