Considering European news is also covering this issue and the rioting...
...may I ask a question or two, in order to ascertain a few facts :
1. Are LEOs in the area equipped with pepper spray ?
2. Are LEOs equipped wirh a baton ?
3. Are LEOs in the area equipped with a taser ?
4. Are the handguns issued to LEOs in the area set on full-auto mode only ?
Because the one thing which is difficult to understand to the "Plain Joe" guy here in Europe , is ...
...why didn't the LEO spray the guy, or use the baton to defend himself from Mr. Brown ?
(considering Mr. Brown was unarmed, the most bodily damage he could have caused was a slap in the face or a black eye at worst)
... why didn't the LEO use the taser to immobilize Mr. Brown from a distance ?
... having decided to DRAW... why didn't the LEO fire the famous warning shot in the air (as is common protocol here in Europe) or
shoot him once in the leg to drop him ?
The four shots in the arm show that Mr. Brown was trying to defend himself, it is an instinctive gesture to cover oneself with the arm(s), hence,
the LEO fired at Mr. Brown at least 5 times too many.
All the evidence
we are fed through the news say the LEO, black eye or no black eye, killed Mr. Brown through ruthless violence, going well beyond any acceptable and necessary force.
That said, my own personal experience in the US (1968 - 1973 as a schoolboy in Virginia, and as a regular visitor twice/year from 2003/2011 shows America is inherently a more violent society than anywhere in Europe.
Fights among schoolkids are egged, confrontations are provoked and almost encouraged, and people are educated to "take things into their own hands", which often sparks family feuds... not to mention neighborhood gangs...
Even in stereotyped mafia-ridden Sicily things aren't as violent as in some parts of the US...
