From the recent discussion about hand loading carry ammo, there is something that I think is being missed: equipment choices are cumulative in the minds of the jury.

Lets take an extreme hypothetical situation:
1. Subject exits his car and proceeds to cross the parking lot to enter a grocery store.
2. Subject is attacked by a known, violent, felon in a manner that clearly poses a lethal threat.
3. Subject responds appropriately with deadly force, shooting the attacker with his licensed, concealed, handgun (this is clearly a “good shoot”, with lots of witnesses.)
4. Police respond and investigate.

So taken at face value this is triumph for law abiding citizens, concealed carry, and the 2nd amendment. Now let me start adding a bunch of strange equipment and behavior to our hero:
- His (primary) handgun is Desert Eagle .50AE with a laser and a flashlight.
- He has 5 magazines for his primary handgun.
- All of his ammunition is hand loaded and he made his own jacketed bullets to some exotic specification.
- He is carrying secondary and tertiary handguns, with reloads for each of them.
- He is carrying 4 folding knives (of legal length in the jurisdiction), of a type originally designed for sentry removal and issued to the navy SEAL teams.
- He is wearing hard body with rifle plates and a ballistic helmet.
- “Born to Kill” and “I am justice” are written on his helmet.

Admittedly, this is hyperbolically weird, but all of this gear is legal (at least for the sake of this argument.) In the eyes of the extremely paranoid he is “well prepared” to buy a pack of hot dogs at the grocery store, but a lot of people would say he is “looking for trouble.” Some of the people in the “too much gear for a shopping trip” camp are very likely to be the witnesses, responding officers, prosecutor, the jury, the media, and the general population.
