Two cops got shot, the executive arm of the government has significant issues as a result. No other conclusions can be made.
Not sure why the response to cop-killing is so hefty, isn't it fairly common in the US? Isn't it to be expected sometimes? It's a bit wild west, but that's nothing new in America.
Further I do not see any problems solved by privatizing violence (or, actually, policing). If you'd like policing to change, use the democratic means to do so. If you don't like the democratic means, fix that. It's vital. If you're a libertarian you're usually still democratic of sorts.
