watch - a useful command.
Communities too need to "watch" out and sometimes act quickly. "hue and cry" has semantic traces back to watching out for seasonal fish from the shores, then actually evolved into a legal practice in England, where neighbours were obliged to come in aid of felony alarms until the practice was repealed in 1827. Watching for dangers, raising alarms, and rushing aid are part and parcel of community life, and being able to delegate some of these activities to commands like watch, could make life a little easier.
