Cell phone charger or a good battery backup for the cellphone. A few of our guys had battery issues when the tornadoes hit here, got caught underprepared.
Flashlights and knives... when you need one, you need one. Never can have too many. I keep a decent light and knife in every car/truck in addition to the one I carry every day. Asp baton or a spring loaded glass breaker to safely remove a window from a burning house or a wrecked car is huge. Nobody here really uses the baton as a baton anymore, it is a good glass breaker though.
I’ll second the S&W M100’s, I carry two pair. Gloves, spare magazines, and a jump box for helping stranded motorists. I’ve seen people run out of gas, run the battery dead trying to start the car. A jump box is something a community minded helper/officer will use. Air compressor is another thing we’ve used, a family’s spare was low on air, got them on their way without a tow truck because an officer had a small compressor. Sure made their day.
