The hole In the door

[L Verge]

It's another one of those puzzlements that will likely never be solved. I tend to think that the Ford statement was made in order to deter people from thinking that they (the theater proprietors) had been lax enough to allow Booth time to do this. Since Lincoln seldom came with guards, why worry about such a peep hole? But then, security was a foreign word to what we think of today.
