I you kill someone be ready to explain why that was the best option. You will talk to an investigator and possibly even a prosecutor. Even if you shoot and miss then the guy gives up your going to need to answer for it. I do know that the standards for LEOs are much more strict than civilian standards but just having a CHL doesn't mean you can go wyatt earp on some bad guys w/o explaining why. Then there's also civil court where the persons family comes in and paints the bad guy like an angel who'd never hurt anyone. Their attorney is going to point out all the specialized knowledge and tools you have. You will need to explain all your choices. I'm not saying you will be wrong I'm just pointing out that you will have to prove that you were right. It's similar to if someone breaks into your barn and gets severely injured falling on some equipment. In todays world you'd be taken to court and have to explain why your dangerous equipment was there and that it was not there as a trap. If the time comes do it to it but never shoot to kill shoot to stop.
