Yep I've taken pics Outside of a Maximum Security Prison also In fact every picture I've taken literally has been outside of a Maximum Security prison being I've never taken a picture inside of one.
But this is not what I said. I said go and stand on a public road and take pics of a Max Security Prison not of kids in a field next to one or turkeys or whatever. Make it obvious that you are indeed taking pics of the prison and in view of the security force of same and when they come out and tell you to move along tell them you know the law etc.
In Lucasville Ohio a fella stood on the public roads and took several photos of the Max Prison from same and when some gub'ment types showed up he told him how was within his rights and he wasn't leaving and they scarfed him up and had a little private powwow and when he left he had his camera and no pics. They explained how the patriot act made things real easy for them to charge him with a crime that could put him away for years.
This happened in 2012 IIRC and it did not make the papers even though he was on assignment to get some pics for a local paper. But that fella has never gone back to take more pics as far as I know.
