We're not a terrible species, Aceman, jus' capable of terrible acts; jus' like any other creature on this planet. And we do kill for survival jus' not always. And we're not the only creatures that kill outta spite or malice or any other reason other than survival. Case in point take dolphins for instance, male dolphins will accost a female, that has recently givin' birth, kill it's baby; and it's all jus' so that they can mate wit the female and produce their own off-spring. A male grizzly bear will kill, even eat, a grizzly cub; no matter the sex of the cub; and the only reason that scientists can figure why is that the male is eliminatin' compitition. The capacity for great cruelty exists in all the creatures of this earth, as is the capacity for great kindness. Is mankind capable of great and cruel acts? Inna word Yes. R we the only species that does? No. Like u said 6.7 Billion ppl r on this planet and we're not all gonna b nice ta one another, but we have the capacity ta learn, adapt, and evolve inna a way that other species r incapable of. We won' b able ta end violence, but we can make sure that those who break the laws r given there jus' do. R things like this gonna continue ta happen? Undoubtedly, but we shouldn' despair. This is why mankind has developed judicial systems, ta help protect us from our greatest threat, ourselves. But jus' like anythin' that mankind has a hand in, it's far from perfect. However it would b less than that if we didn' have it.
That bein' said, as far as "there's nothin' bein' done" is concerned; it could b that the investigators may not have enough evidence ta officially charge the perpetrators. Or it could b that the lack of action could b racially motivated, or 'cause, as u have stated urself Starfire1036, of the connection between one of the perpetrators and the investigators. We simply do not know and 'til somethin' is done, we simply won'. Things like this take time, one can' expect action overnight. Have a little patience and an outcome will happen. I read an article in a newspaper one time where a father, a detective, who arrested and turned in his own son for a robbery; after a 6 week investigation. Jus' 'cause one of the perpetrators is the son of one of the police officers there doesn' mean that the officer will not arrest him, or her, for this crime and turn them in. Yet it doesn' mean that the officer will either, we jus' simply do not know and 'til the outcome reveals itself, it'll still b up in the air what will happen next.
