Twelve dead, including Police officers, dead for doing less offensive things than I've done, does not sound like a "bandwagon".
I've been in countries where you did not dare take a newspaper to breakfast, lest you "soil" the picture of the fearless leader on the banner, a crime punishable by death.
If I want to be able to say something offensive about someone else's beliefs, I had best be ready to allow them the same right. I've never killed anyone for mocking my religious beliefs.
"Bandwagon". Funeral march for a bit of liberty would be a better description.
