Think about – there are lots of special interest magazines for specialized interests:

House and Garden (home decorating(
Guns and Ammo (firearms enthusiasts)
Stamp and Coin Monthly
PC World and PC Magazine
Horse and Hound
Boy’s Life
2600 (hackers)
Modern Woodworking
and so on.

Is there a magazine published for, say, bank robbers? Murderers? Embezzlers?

It seems like there should be “how to do it” articles for any of the above – just like you see in the other special interest magazines. Would there be a market for that?
