Another case of intentional murder of police, this time in Baton Rouge, Louisiana...

...site of a highly publicized police killing of an African-American man a couple of weeks ago.  The only thing this guarantees is that there will be more police shootings of innocent people, since increased and justified paranoia among police in certain neighborhoods will now be the norm:  those afraid of being shot are more likely to fire in what they take to be self-defense.  (Earlier coverage of these issues here and here and here.)  The only possibly hopeful note is that just maybe this kind of violence against the police will lead to stricter gun control.  I admit that is a remote hope.
