I'll loosely paraphrase what a man who I have a world of respect for told me when I asked him that same exact question: It's the same ammo used by law enforcement professionals. No more, no less. It's not any more inherently "evil" or "deadly" than any ammunition you can purchase at a sporting goods store. If anything, it's high quality ammo meant to perform to more stringent standards.
I'll also share an experience I had a while back when my vehicle got totalled by another vehicle that ran a stop sign and I had to be taken to the hospital in an ambulance. Since I didn't want to leave my handgun in the vehicle and I couldn't bring it with me, I handed it to the responding State Trooper for safe keeping. At the time, it was loaded with Winchester Ranger RA9T rounds. I experienced no suspicion or doubt from the Sergeant on duty when I came to collect it after the accident, and I'm sure they noticed what ammo was in the chamber and magazine.
