Don't make me come up in here with a big, ol' can of "it depends."
Bac, yes, that is one school of thought. However, the more important consideration, at least to this tilecrawler, is "
WHY" you choose a certain ammunition.
He's a little something I picked up in my LEO daze, write this down: THE JURY ALWAYS WANTS TO KNOW WHY. Be ready to present a logical, reasonable answer to: why did you have a gun? Why did you go in there? Why did you shoot him? Why did you use that pistol or that ammo.
Prepare for Problem #2 just as you train for Problem #1. Prepare to explain your actions and your selection of gear.
[scene: Superior Court XL II, THRland, the honorable El Tejon presiding]
Madam Persecutor: "You vile, eeevil gun nut. How dare you shoot poor little Cledus "Ra-Ra" Lee Longstreet Lee. Why did you use such eeevil ammunition of death."
THR Defendant in the dock: "Well, ummm, it's what the cops carry, I guess."
Persecutor: "So, you're a Batman, huh? Trigger happy cowboy in a silly hat and pointy elf shoes? I'll bet you went to gunfighter school to learn how to kill women and minorities faster and more brutually? Isn't it true you're a mad dog killer and selected the most eeevil bullet you could find?"
THR Defendant: "No, ma'am, I based this choice on several factors that I learned about in my safety classes. The first factor being safety. I choose a hollowpoint as it is more likely to be contained in the threat, like Mr. Lee, and reduce the chance of injury to bystanders. As well, hollowpoints are less likely to ricochet and hurt bystanders. Thus, out of concern for others I chose this ammunition. . . .[und so weiter]"
Hon. El Tejon, Judge: [bangs gavel] "Alright, I've heard enough. Judgment for Mr. THR based on insufficient evidence. I'll see the hot looking newsbabe in my chambers. Bailiff, go light the candles and put on the Norah Jones album."
