IPv4 smaller than /24 leasing?

[lists at mtin.net (Justin Wilson)]

I am looking at it from an ARIN justification point.  If you are a small operator and need a /24 you have justification if you give customerâ??s publics, but is it a great line if you are only giving out publics for people who need cameras or need to connect in from the outside world. If I need a /24 and I donâ??t really use it all am I being shady?  It becomes a â??how much of a grey area is thereâ?? kind of thing.
