For justice, outcomes matter. This is why there is a difference between "attempted murder" and actual murder. Yes, both are punished, but the actual outcome does matter. Therefore, the distinction between a flashbang and an incendiary/fragmentation grenade (which what most people think when they read hand grenade) too does matter. When I read the initial statement, I thought that the child was killed and am happy to hear that thats not the case. Even though the child was definitely harmed, I am happy that it is still alive.
