Uhh, no, this is totally wrong. Again, it's not about whether the bullet can kill someone, it's about whether it can reliably and rapidly incapacitate them. This depends on penetration and wound channel diameter. All bullets are capable of killing someone, but not all bullets are capable of reliably and rapidly incapacitating them. .22 LR is not capable of the latter. End of story. .22 is therefore a terrible choice for defensive use. There is a reason that virtually every single self-defense instructor, firearms expert, etc. will tell you that .22 is an inadequate round for self-defense.
