F.B.I. At Work -- The two agents quickly overpowered the fleeing man, and here they make him lean against the wall as they search for concealed weapons. Another agent in the distance can be seen closing in to shut off any escape. Also note that agent John Doe, who is doing the searching, keeps his foot in front of the suspect's left foot. In case the latter should try to make a break, he can easily be tripped up in his "off-balance" position. April 11, 1952. (Photo by United Press).
