"A commercial, and in some respects a social, doubt has been started within the
last year or two, whether or not it is right to discuss so openly the security
or insecurity of locks. Many well-meaning persons suppose that the discus-
sion respecting the means for baffling the supposed safety of locks offers a
premium for dishonesty, by showing others how to be dishonest. This is a fal-
lacy. Rogues are very keen in their profession, and already know much more
than we can teach them respecting their several kinds of roguery. Rogues knew
a good deal about lockpicking long before locksmiths discussed it among them-
selves, as they have lately done. If a lock -- let it have been made in what-
ever country, or by whatever maker -- is not so inviolable as it has hitherto
been deemed to be, surely it is in the interest of *honest* persons to know
this fact, because the *dishonest* are tolerably certain to be the first to
apply the knowledge practically; and the spread of knowledge is necessary to
give fair play to those who might suffer by ignorance. It cannot be too ear-
nestly urged, that an acquaintance with real facts will, in the end, be better
for all parties."
