Wrong.
Everyone I know (4 so far) who have availed themselves of the informal review process have been granted a Maryland handgun permit.
In fact, I don't know anyone who has appeared in person and has been denied.
One hard head allegedly demanded a informal review by phone and was awarded with a result commensurate with his investment. Not that it's right, but you have to play to win.
Guess you haven't seen the Mike Smeigel video then......
