Was watching a Youtube vid and saw Monk Eastman also was into pigeons.
Anthony Spero, Sonny Black, Casso (Liked killing them apparently)
Even Mike Tyson had the love for them.

I am sure there are other gangsters that loved these birds for an unknown reason to me.

I can only speculate that being that they aren’t indoor birds, it may have given them the freedom to speak there mind freely to them. In the same manner just as we do to our dogs. Like a therapist that just listens.

Anyone know what the possible attraction of pigeons and gangsters could be?
