Sorry Simon. But I really don't think you understand the social issues in America. I don't see how guns is the root cause for the riots going on or the issues between the Black community and the police. You didn't even make an attempt to justify that statement.
I'm for strict gun laws, but I know that will have no impact on crime in America. Guns are in the 100's of millions in this country.You literally would have to ban guns and gather them all. There are 89 guns for every 100 American. This will never happen since it is now part of our Constitution with the 2nd Amendment. It would have to be appeal, and will not happen any time soon. The best is with strict gun laws, and that as I stated has no impact in America. According to the 2011 FBI Uniform Crime report, Californian with the strictest gun laws in America based on the Brady scoring system , had the highest amount of gun murders in 2011.
Though the rest of your argument/comments I see validity in. I think you are way off on racism not being a fundamental issue, and really don't think you have an understand of the dynamics of it pertaining to America. To just touch on you Marijuana/Drug comment. If needed I can provide you source, but Whites use Pot just as much if not more than Blacks in America. However, look at the arrest report below. Can a correlation be made between race and arrests? Racism, poverty, guns, drugs, education, ect... are all valid issues to this problem.
