How can a god, that apparently loves everyone, allow this kind of thing to happen?

[Esquilax]

Strange that we want God out of our day-to-day lives (and our schools and our politics) when it suits us but when (godless) criminals commit a crime (sin) we expect God to intervene.

It's also possible that you can take the question as a hypothetical, like it was intended.

Also, just saying, the prayer invocations in your government and the ability of every school student to pray according to their conscience assuming it doesn't disrupt classes kind of puts the lie to your "god out of schools and politics," bullshit.
