This should make for interesting observation.
On the subject, firsthand and upclose experience tells me that because a person is not carring a fiream does not mean they are unarmed. In this case I think the released retail store video demonstrated Mr. Brown carried and asserted himself as a weapon of force when he wanted to, which sometimes he evidently did choose to do. Whatever the grand jury finds and whatever evidence it used for that finding will be closely scrutinzed and rightly so. I fear this whole episode will go down in history as one more thug whose bluff was called and his gamble ended up costing his life.
We are not guaranteed tomorrow so we better put today to good use. That is, if we want to be a productive member of society. If we want our children to mature and have a productive life then now's the time to teach them how to improve that potential by doing simple things like takeing care who they hang out with, where they go, when they go there, how they dress, how they conduct themselves, pursuing education etc. If a person grows up playing with fire he's likely to get burned sooner and more severe than the person whose parents taught him or her not to play with fire and made sure of it while they still had a say about it. Asserting your physique in the known presence of a firearm is literally playing with fire! I'm not saying this is what precipitated the shooting of Mr. Brown. But I could easily envision that in my head based on something that is known. The man carried himself as a thug.
I know a lot of successful individuals. I don't know one who asserts his physique as threat to steal a handful of cigars. A person who does the latter is less likely to live long or grow up to become a productive member of whatever society they live within.
