"One would really be better off carrying a set of bolt cutters, a power drill, or a sledge hammer, rather than a set of lock-picks, if you really need to get into a locked door."
For most common house doors, a large pair of vice-grips will do the job. That's what they were using around here some years ago: open, clamp, twist and they're in. Many of the locks now have plastic parts inside -- whose bright idea was that?

A couple of years ago I got locked out when the latch mechanism inside the deadbolt broke. It took the locksmith about 10 minutes with a pair of channellocks to get in. Also, most interior locks can be defeated with a strong grip and a hard twist.
