 An initial distinction here is between single one-off actions of corruption and a pattern of corrupt actions. The despoiling of the moral character of a role occupant, or the undermining of institutional processes and purposes, would typically require a pattern of actions—and not merely a single one-off action. So a single free hamburger provided to a police officer on one occasion usually does not corrupt, and is not therefore an act of corruption. Nevertheless, a series of such gifts to a number of police officers might corrupt. They might corrupt, for example, if the hamburger joint in question ended up with (in effect) exclusive, round the clock police protection, and if the owner intended that this be the case.
