Get used to this kind of thing happening wherever you find Muslims.
The proper response to any situation like this one is to treat the Islamist as an immediate mortal threat and use lethal force to neutralize the threat.
Yeah, but you MUST NOT FORGET that this has NOTHING to do with islam.
The Muslims have been desecrating churches in Europe for two years with little outcry except when they murdered that priest.
The difference is that this man went where there was an audience.
To kill or be killed in the name of Allah, so the obvious remedy is to first recognize it, calling it by it's proper name, something Obama could not bring himself to do and then kill it.
