They're watching you
Case in point: One day I changed vehicles with my wife, who’s a jail administrator. That day, four different inmates reported to corrections staff that someone was stealing her vehicle! This kind of inmate awareness should serve as a reminder of how alert we also need to be. If inmates know where you’ll be and when and what car you drive, that information can be used to plot a revenge attack. You should stay alert to that, take measures to make yourself more unpredictable (see Protecting yourself & your family from retaliation), practice when/then thinking so you’re more prepared to defend yourself when necessary and carry off duty.
