Laws catch flies, but let hornets go free.

The saying criticizes unequal enforcement: rules are readily applied to small, weak, or insignificant offenders, while powerful or more formidable wrongdoers escape restraint. Its imagery is metaphorical, contrasting easy targets with those harder to challenge.

Its contrast suggests that legal systems can appear strict without being just. Punishing easy targets while excusing those with influence undermines the law’s claim to impartiality; it should not be read as endorsing stereotypes about particular kinds of people.

Use it when discussing selective justice, especially where minor breaches receive penalties while serious misconduct by stronger or better-protected people goes unpunished. It is a pointed criticism of institutions, not a neutral description of legal procedure.
