I'm unique for a suspense author in that I don't have a specialty background. A lot of suspense writers used to be lawyers or crime beat reporters. I didn't even know a cop when I started out. I finally figured out that I could visit prisons - I just had to be willing to make the phone calls.
There are plenty of bad actors and there are plenty of bad directors. There are actors who will always be bad and there are good actors who you cry for because they're being badly directed or the material isn't good enough.
