from the interview i saw , the members didn't know it was legal to carry to church/temple , remember concealed carry was less than 1 year old and had around 100,000 licenses at that point state wide so even if they knew it was legal it is statistically improbable that anyone would have been carrying , yes open carry had been legal but besides those on this site and a few others it just isn't that common either and is practiced by a even smaller portion of the population that carries , as we get closer to 2 years of concealed carry we get closer to 200,000 I expect we will reach it before 2 years. this is faster than many states have grown concealed carry , and will be a bit more than 5% of eligible , but that still puts about 1 in 30 of general population licensed to carry in Wisconsin that will double the chances of someone carrying in a church or place of worship but depending on the demographic it still may be unlikely at some.
I don't know if it was or was not but guessing that if the members didn't know it was legal they also didn't know to post,Sikh like many most religions teaches peace and non violence , and many take that to mean no defense either far to many see a gun as a tool for hunting or a weapon to hurt people , this is a narrow minded interpretation , a gun , a pistol ,a handgun is a tool that can be used for good or evil but mainly it is a tool for defense of good people millions of times each year in this country, the gun doesn't make the the person good or bad , the person makes the person good , neutral or bad
so much of the state was oblivious to it as they had not been following the change in law like , the posters here.
but as Firearms instructor pointed out , every building owner or lessee makes their own decision , if you want to post the sign must be 5x7 inches and plainly posted at each possible entrance to the building or portion of a building that prohibits carry or a particular type of carry or weapon
after the temple shooting , I was talking with a Muslim friend who said , a few of them had started carrying to mosque
I know some churches the pastors carry , others post , my church is un-posted and i know a few carry
