That probably could be proven by going through arrest records. I just don't see the reason to now show it. Just like that old mug shot of Frank Sinatra floating around the net. If someone was motivated, that could be found.
The code no longer exists. There is no shame in the scene. Nothing to defend.
Those sorts of things happened then and now. Its a part of life. Out of sight, out of mind really doesn't work anymore. I thought it was done respectfully, nothing explicit.
"In those days", a gay man could be arrested for just having gay pornography.
"In those days", they tried to arrest Lena Horne and her white husband in the south after one of her concerts,but she was warned and fled the scene.
And " in those days", black people were arrested for sitting in a Woolworths in the South asking for a cup of coffee and they were arrested for sitting in the whites-only waiting room at a bus station.
"In those days", people were arrested for just being normal or doing things that we would call normal today.
It's always a good idea that we remember this, so that we don't have to go back to "in those days"--anytime soon.
