Sunday’s murders of three police officers in Baton Rouge, Louisiana made Monday’s “Law and Order” theme at the Republican National Convention resonate louder.

Donald Trump has proclaimed himself the “law and order candidate” and criticized President Obama’s leadership on the issue in a Facebook post Sunday.

In a televised statement Sunday, Obama said “nothing justifies violence against law enforcement.” Monday he sent a letter to the National Fraternal Order of Police, expressing gratitude for the work of law enforcement officers, acknowledging the dangers they face and the valor in which they perform their duty.

But for some, Obama’s supportive words for police ring hollow because he has also voiced concern and understanding for blacks who have been killed by police under questionable circumstances.

As the Republican and Democratic conventions play out over the next two weeks, the political rhetoric about race and police will likely continue.
