Hey jmannix,
One of our Wing Chun Instructors in Melbourne is a Constable of some sort within the Australian Police department.
I've also known a few police officers go through our school as well.
Not saying that WC is the be all and end all, but something you may want to check out.
Most schools do free trials/cheap intro offers. Go check out a few in your area.
Hope you find it.
