Is it a big city courthouse or small county seat?

Is your car parked close by on the street or blocks away?

Is there a nearby location that you can stash a small cache of tools?

How close is the nearest medical station (hospital/clinic/fire station)?

Are you up many stories or less than four stories?

How far away is sanctuary (home/office/friend's place)?

My recommendations:
1. Signaling - whistle, cell phone, flashlight, laser pointer, and orange bandana
2. Tools - ResQMe seatbelt cutter, flashlight (same as used for signaling), 10' metal tape measure, duct tape, zip ties, battery or crank powered cell phone charger, P38 army can opener, eyeglass repair kit, sewing kit
3. First aid - small kit with assorted guaze pads, bandaides, antiseptic wipes, ace-bandage, moleskin blister pads.
4. Person protective clothing - 95N dust mask, weather-appropriate hat, spare glasses, good shoes, small umbrella, and leather gloves. Sidenote: get your lenses made of polycarbonate material for extra protection.
5. Food/Water - 1 liter of bottled water (if allowed), otherwise scope out potential sources of water/juice/soda. For food some granola bars and beef jerky.
6. Self defense - car keys, aluminum briefcase, roll of quarters.
