No details as to who or why, but someone shot up a Sikh temple in Milwaukee (how's that for our melting pot in action?) earlier today; the body count is six plus the shooter, who was "put down" by a policeman.
Sikhs often get confused for Muslims, as they come from India (and thus have darker skin), wear turbans and beards; they aren't Muslims but an Indian hybrid that tried to unite the Hindus and Muslims of the subcontinent.
One interesting footnote in Sikh garb is a small dagger, a kirpan, that Sikh men are supposed to have on themselves 24/7. In a post-9/11 universe, that gets some raised eyebrows and often comes afoul of concealed-weapon laws, creating a good First Amendment free-exercise trip to the courts in many cases; an Italian case was in the news last week.
However, ker-pow trumped kirpan in this case. It will be interesting to see what might have motivated the shooter and whether is was a mistaken-identity issue of taking out frustrations on Muslims on South Asia folks who kinda look the part if you don't know your cultural geography.
