Maybe it's a conspiracy theory, but in any cases, it is still interesting:
In a novelty case located on a wall in Ford's Theater is 'The Gun That Shot Abraham Lincoln.' If anyone (assassin) were to kill a head of state, they would use a revolver, because several bullets might be needed to accomplish the murder and stop any guards during the escape. One would only use a one-shot pistol if they were absolutely sure they had intimate access to the victim. The gun on the wall of Ford's Theater is a derringer - the perfect weapon for the left handed female assassin who did not attend her husbands funeral. Mary Todd was not hiding in her room due to overwhelming grief and sorrow; she was imprisoned in her room with two armed guards for two weeks after killing her husband.
We can see on this pic a small market and the minaret of an old mosquee that was in the place of the Church.
Some slums and low cost residential areas.
