Like ants, expect a migration out of concentrations into dispersion. "The big stuff" they do not have, at present, they will steal, if they are able. Watch your stuff. Gangs begin this way to create a sense of "might is right" as intimidation of We The People, some of whom are unsuspecting and do not know the hoard is coming.
Be vigilant my soul. Be swift my feet. Refuse to be a Victim.
