It means a man who was murdering people on the regular for power less than two months ago needs a little more time absent murder and attacking people before I'll consider giving them more of a leash. I appreciate that you want to help him and everyone in Norfinbury by extension, Al, but this isn't a burden you need to bear. He attacked Sherlock only recently. That doesn't inspire a great deal of confidence in me that he won't try to attack you.
