And I'm sure we can all come up with things that he could have said to pretend he cares, but he's the President, he should care. In fact, it's his job to care.
Of course, he couldn't be bothered to pretend to care either.
I think we all know how he would have responded if Muslims were involved though. Which kind of gives up the game doesn't it? He doesn't really care about keeping us safe, he just knows it's acceptable to his voters to scapegoat Muslims under the guise of keeping the country secure. It's all a bunch of bullshit. Which is why a stabbing by a Muslim in Europe is immediately tweeted about and six Muslims gunned down in Canada aren't mentioned at all.
Jews and Muslims being murdered doesn't play as well with his voters as Muslim terrorism does.
